sys-kernel/coreos-modules: compress modules with xz

Compress every kernel module with xz (lzma), to make more free space
in the rootfs.

```
$ 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
