Make lsb_release optional; drop unavailable lsb packages from CI

redhat-lsb-core is absent from EPEL 9 and redhat-lsb is gone from Fedora 44.
lsb_release is only used for log messages and DEB package naming on Ubuntu/Debian,
neither of which applies to RPM builds. Degrade gracefully with a warning instead
of a fatal cmake error when the binary is not present.
