bpf: Enable retrival of pid/tgid/comm from bpf cgroup hooks

We already have the bpf_get_current_uid_gid() helper enabled, and
given we now have perf event RB output available for connect(),
sendmsg(), recvmsg() and bind-related hooks, add a trivial change
to enable bpf_get_current_pid_tgid() and bpf_get_current_comm()
as well.
