selinux: rhbz1633211 bpf class & inheritence issues
Not only add bpf class checks/rules, but add --common flags (where
applicable) to catch the permissions where the class access type is
inherited.
This should (hopefully) solve the issue on newer selinux versions
where the user space tooling can report inheritence, and opts to omit
large potions of the class access types.

Thanks.
