Actually support Ubuntu

[TJ]

[impact]

mkosi does not work on ubuntu when using distribution detection instead of specifying distribution and release codename

[test case]

see original description

[regression potential]

any regression would likely result in immediate failure on ubuntu and/or when running mkosi for ubuntu

[scope]

this is needed for f,g,h

this was fixed upstream by commit 743a06b0afd1215c4a63e7f30d8f10a128d07293 which was first included in version 6, so this is needed in h and earlier.

this is also needed for b, but that version is so old that it would require other changes

[other info]

https://salsa.debian.org/systemd-team/mkosi/-/merge_requests/2

[original description]

version 5-1 does not support Ubuntu correctly in that it tries to use the version number rather than version codename in arguments to debootstrap.

Notice the "20.04" argument passed to debootstrap, which should be "focal".

This applies for 21.04, 21.10 and 20.04

I adjusted the patch slightly to match the upstream commit, and uploaded to f/g/h.

Thanks!
