audit: log 32-bit socketcalls

[ Upstream commit 62bc306e2083436675e33b5bdeb6a77907d35971 ]

32-bit socketcalls were not being logged by audit on x86_64 systems.
Log them.  This is basically a duplicate of the call from
net/socket.c:sys_socketcall(), but it addresses the impedance mismatch
between 32-bit userspace process and 64-bit kernel audit.
