AF_UNIX: Implement SO_TIMESTAMP and SO_TIMETAMPNS on Unix sockets
Userspace applications can already request to receive timestamps with: setsockopt(sockfd, SOL_SOCKET, SO_TIMESTAMP, ...) Although setsockopt() returns zero (success), timestamps are not added to the ancillary data. This patch fixes that on SOCK_DGRAM and SOCK_SEQPACKET Unix sockets.
