selftests: livepatch: save and restore kprobe state
Save the state of /sys/kernel/debug/kprobes/enabled
during setup_config() and restore it during cleanup().
This is in preparation for a future commit that will add a test
that should confirm that we cannot livepatch a kprobed function
if that kprobe has a post handler.
