perf bpf filter: Add uid and gid terms
Allow the BPF filter to use the uid and gid terms determined by the
bpf_get_current_uid_gid BPF helper. For example, the following will
record the cpu-clock event system wide discarding samples that don't
belong to the current user.
$ perf record -e cpu-clock --filter "uid == $(id -u)" -a sleep 0.1
