Implements test cases for the kernel version compatibility check in
`pbs2to3` for a set of expected and unexpected kernel versions.
Suggested-by: Maximiliano Sandoval <m.sandoval@proxmox.com>

The kernel versions in the test cases were mostly hand-picked from the
current Proxmox Backup Server repositories, excluding the kernel
versions 5.19.* and 6.1.* because they were both not expected before
this patch. Also, they are tested for both cases, when PBS was already
upgraded to v3.x and when PBS is still on v2.x.
differences to v2:
- removed unnecessary .iter() call in test loop
- retyped kernel versions from Vec<_> to &[&str]

Sorry, forgot to check for newer versions of the patch series, so
answering again as it's still relevant:
In PVE and PMG we allow arbitrary newer -pve kernels for
future-proofing, it would be nice to do the same here too:
