net: diag: allow socket bytecode filters to match socket marks
This allows a privileged process to filter by socket mark when dumping sockets via INET_DIAG_BY_FAMILY. This is useful on systems that use mark-based routing such as Android. The ability to filter socket marks requires CAP_NET_ADMIN, which is consistent with other privileged operations allowed by the SOCK_DIAG interface such as the ability to destroy sockets and the ability to inspect BPF filters attached to packet sockets.
