Remove configure probes for sys/un.h and struct sockaddr_un.

<sys/un.h> is in SUSv3 and every targeted Unix has it.  Some Windows
tool chains may still lack the approximately equivalent header
<afunix.h>, so we already defined struct sockaddr_un ourselves on that
OS for now.  To harmonize things a bit, move our definition into a new
header src/include/port/win32/sys/un.h.

HAVE_UNIX_SOCKETS is now defined unconditionally.  We migh remove that
in a separate commit, pending discussion.
