Linux Socket Filters can already be successfully attached and detached on unix
sockets with setsockopt(sockfd, SOL_SOCKET, SO_{ATTACH,DETACH}_FILTER, ...).
See: Documentation/networking/filter.txt
But the filter was never used in the unix socket code so it did not work. This
patch uses sk_filter() to filter buffers before delivery.
This short program demonstrates the problem on SOCK_DGRAM.
