nbd sockets vnc: Mark problematic address family tests TODO

Certain features make sense only with certain address families.  For
instance, passing file descriptors requires AF_UNIX.  Testing
SocketAddress's saddr->type == SOCKET_ADDRESS_KIND_UNIX is obvious,
but problematic: it can't recognize AF_UNIX when type ==
SOCKET_ADDRESS_KIND_FD.

Mark such tests of saddr->type TODO.  We may want to check the address
family with getsockname() there.
