Cygwin: move sun_name_t constructors into fhandler_socket_unix.cc

Browse Source 
They are only used there anyway and it allows to use the AF_UNIX
macro without tweaking header files.  While at it, improve
both constructors.  The default constructor now creates the name
of an unnamed socket, the constructor taking parameters carefully
checks its input.
