CI: Move various things into proper places

[andrewbird]

I found this tidy up that had been hanging around here since last June, so I rebased and made a PR.

I think this CI currently fails.
So will have to wait.

By the way, copilot says there is
a kvm on github runners, just permissions
are not set up. Is this true?

[andrewbird]

Yes, we enable it for some dosemu testing, but not fdpp and others.

[stsp]

Thanks!

[andrewbird]

Note: Although the dosemu spat out this message, I don't think it could have exited with an error code as the test still passed.

ERROR: KVM: error opening /dev/kvm: Permission denied
ERROR: libao: unable to open output device
ERROR: Unable to open console or check with X to evaluate the keyboard map.

Landlock ABI 3 but LANDLOCK_ACCESS_FS_REFER not defined
ERROR: landlock_init() failed
ERROR: kbd: EOF from stdin

[stsp]

Yes, these are not fatal.
I just clicked "Explain failure" button
and copilot said I can enable KVM.
The real problem was that
LANDLOCK_ACCESS_FS_REFER not defined,
but this wasn't logged in the prev versions.
I just added such logging together with the
related fix, as I suspected that could be the
culprit.
