[PATCH] SELinux: map Unix seqpacket sockets to appropriate security class

This patch for SELinux fixes a bug in the mapping of socket types to
security classes and ensures that Unix seqpacket sockets are mapped to an
appropriate security class.  The Unix stream security class is re-used in
this case as it has the same permission checking applied as for seqpacket.
