pve7to8: Fix Fedora 38 systemd unified cgroupv2 check

For Fedora 38 the systemd shared object files used to check the systemd
version are located at /usr/lib64/systemd or /usr/lib/systemd.
Therefore, include /usr/lib64/systemd in the list of directories to
check.

Further, Fedora 38 adds a fc38 postfix to the filename, so expand the
regex to cover that as well.
