selinux: add proper NULL termination to the secclass_map permissions
This patch adds the missing NULL termination to the "bpf" and "perf_event" object class permission lists. This missing NULL termination should really only affect the tools under scripts/selinux, with the most important being genheaders.c, although in practice this has not been an issue on any of my dev/test systems. If the problem were to manifest itself it would likely result in bogus permissions added to the end of the object class; thankfully with no access control checks using these bogus permissions and no policies defining these permissions the impact would likely be limited to some noise about undefined permissions during policy load.
