Setting the option is handled in sk_setsockopt(), querying it was not handled in sk_getsockopt(), though. For consistency, implement the missing getsockopt(SO_TIMESTAMPING_NEW). Similar as with SO_TIMESTAMP_{OLD,NEW}, the active timestamping flags are only returned when querying the same SO_TIMESTAMPING_{OLD,NEW} option they were set for. Empty flags are returned with SO_TIMESTAMPING_{NEW,OLD} otherwise.
