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.
