We can now use Gentoo's upstream ebuild, save for a few small overrides
in a separate env file.
This bumps GRUB from 2.06 to 2.12, The existing two Flatcar patches have
been rebased.

The old version 2.1.4 does not cross-compile without help from QEMU that
we cannot rely on going forwards. 2.1.10 is Meson-based and handles this
much better.
Rather than update the package in-place, migrate it to portage-stable
and cover the differences with a small patch and env script.
Upstream now carries the systemd files, so we do not need to add these.
/etc is now automatically moved to /usr/share/flatcar/etc, so we no
longer need any special handling for that here, but I have added a
compatibility symlink for iscsid.conf.

The coreos-overlay package under app-admin was written by Jeremi around
the same time I added it to Gentoo under sys-apps. It has had a new
release since.

It is not clear why this was forked originally. One reason was to avoid
the sys-apps/lsb-release dependency, but it probably wasn't just that.
It seems likely that the upstream package did not support cross targets
at the time. Now it does.
It appears that LTO was previously enabled by us following Gentoo rather
than through an explicit decision. They now disable it by default, so we
do likewise. It previously used "fat" LTO, which makes Rust especially
slow to build and reportedly made rustc slower than with "thin" LTO!
There seems little benefit in using thin LTO given that we rebuild Rust
almost as much as the packages that use it, plus we don't enable LTO
anywhere else.
We still avoid rustdoc to keep the size down using INSTALL_MASK. This
isn't as good as not building it in the first place, but this alone
isn't worth keeping a fork.
Cross targets are now handled via the admittedly experimental
RUST_CROSS_TARGETS support. This has been in place for a while, and I
think it is fairly widely used now. If it does disappear, it would
almost certainly be for something even better.
This also updates Rust from 1.80.0 to 1.80.1.
