            kernel/selinux-testsuite: improve kernel package detection

Instead of relying on the existing kernel package naming and versioning
conventions, which are subject to change in RHEL, determine the main
kernel package name via `rpm -qf "/lib/modules/$(uname -r)/vmlinuz"` and
derive the rest from that.
