Compress every kernel module with xz (lzma), to make more free space
in the rootfs.
Before:
```
$ sudo du -s /usr/lib64/modules/$(uname -r)/kernel/
90472 /usr/lib64/modules/5.8.11-flatcar/kernel/
$ df /usr
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/usr 1007760 916024 39720 96% /usr
```
After:
```
$ sudo du -s /usr/lib64/modules/$(uname -r)/kernel/
26908 /usr/lib64/modules/5.8.11-flatcar/kernel/
$ df /usr
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/usr 1007760 845468 110276 89% /usr
```
The use flag enables building audisp, auditd, aureport, ausearch and
probably some other tools. Not sure what's the reason for adding such
a use flag other than disabling the build of the binaries. The daemon
use flag is nowhere set, so these things are not built by default.
The savedconfig feature reads and, if not set, generates a file under
/etc/portage/savedconfig/ to source a build configuration. We probably
don't want this and specially not on the final image, therefore,
disable reading and also don't write the file to the final image.
These normally would be pulled by systemdctl enable when enabling
systemd-networkd.service, because they are used in Also= options. In
such case, we need to pull them ourselves, so they can be enabled in
/usr, not in /etc.
We are installing systemd from scratch in the image, so there are no
previously enabled units to enable or reenable after
installation. Also, this code would enable the services in /etc, which
we don't want, because /etc is not autoupdated, so the enabled
services could end up still being disabled after the update.
At installation time, we usually want to enable services through
/lib. This change will stop making the installation to put symlinks
for getty in /etc, since we already do it in /lib.
Since v242, this unit is not enabled by default. Currently the
recommended way of initial enablement of the important units is
through `systemctl preset-all` with the preset file from systemd. We
don't want to do it, because this action creates symlinks in /etc, so
we enable those services ourselves by putting the symlinks in /lib.
Since sqlite 3.32 or newer requires dev-lang/tcl to be available in
the Flatcar SDK by default, we should add dev-lang/tcl in the dependency
list of SDK.
Update srctree path to correctly populate the Makefile for sandbox
environments. The patch is to adjusted for 5.x kernels

The build for arm64 currently fails because it tries to build the
oslogin package but the package is marked as amd64-only.
Exclude the oslogin package from arm64 images.
Since sqlite 3.32.0, Gentoo ebuild does not deal with non-full archive,
but fetches only full archive. On top of that, the upstream sqlite's
full archive requires `tclsh` to be installed on the host system. Since
Flatcar SDK does not include `dev-lang/tcl`, it is not possible to build
sqlite from the full-archive. It means that we need to either make the
Flatcar SDK include `dev-lang/tcl`, (which takes time) or bring back the
non-full archive mechanism just like ebuilds from sqlite 3.31.x.
So adapt the full-archive patches on top of the non-full archive.
Make the ebuild fetch the non-full archive.
GCE recommends images to ship Python in them. Instead of shipping the
binaries inside our vendor partition, install an alias that will
download the latest official container, for both python2 and python3.
