mod_admin_socket: Compat for luasocket prior to unix datagram support The "socket.unix" module exported only a function before https://github.com/lunarmodules/luasocket/commit/aa1b8cc9bc35e56de15eeb153c899e4c51de82a8 when datagram support was added. Fixes #1717 Thanks rsc and lucas for reporting and testing
