Add pxe-tar-xz to bib types and add boot tests for f43, stream9, and stream10

[bcl]

This does what it says in the subject, in several commits of increasing complexity :)

Mmm, looks generally OK but I think the linter error is cancelling all other tests from running.

I also assume that the boot tests will (eventually) move into images itself once we have bootc-related bits there?

NOTE: Running bootc status from the booted system currently does not
work so that has been disabled until it has been fixed.

I am wondering what is the error?

They'll follow along with wherever the test/bib/ tests move.

I am wondering what is the error?

[root@localhost ~]# bootc status
[   40.058638] SELinux:  Context unconfined_u:object_r:invalid_bootcinstall_testlabel_t:s0 is not valid (left unmapped).
mount: /sysroot: fsconfig system call failed: overlay: No changes allowed in reconfigure.
       dmesg(1) may have more information after failed mount system call.
error: Status: Opening . with writable mount: Failed to remount: ExitStatus(unix_wait_status(8192))

I'm planning on looking into that next.

Seems that Fedora updated its linters (which might run downstream) leading to this error there:

# [github.com/osbuild/image-builder-cli/pkg/progress]
./command.go:189:19: non-constant format string in call to (github.com/osbuild/image-builder-cli/pkg/progress.ProgressBar).SetMessagef
FAIL	github.com/osbuild/image-builder-cli/pkg/progress [build failed]

Let's not address that in this PR but let's also not lose track of it. The RHEL-10 failures are PQC/mock related so also not relevant.

Otherwise this PR looks good. Thank you.

Uh oh. Things got canceled before the new test_build_pxe.py test could run. I'd have liked to see that pass (or mostly work) before merging this.
