Libguestfs - Feb 2023 - [PATCH v2v] convert: linux: Require host cpu for all RHEL-alike >= 9

Already pushed as:
https://github.com/libguestfs/virt-v2v/commit/9f12b95bbe7bc2850ce4ba134c46a3cc5fd1167d

I'm posting to the list for awareness.

Rich.

RHEL >= 9 and compatible distros like Rocky >= 9 will not boot using
the default qemu CPU.  You will see an error at boot:

  Fatal glibc error: CPU does not support x86-64-v2

Instead you need to use -cpu host.

In commit f28757c6d1 ("convert_linux: set "gcaps_default_cpu =
false"
for x86_64 RHEL-9.0+ guests") we fixed this specifically for RHEL >= 9.

This commit extends the same fix to all RHEL family distros.

Updates: commit f28757c6d100060c65212ea55cfa59d308dcb850
Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=2166619
