c69c850df4 Cygwin: AF_UNIX: sendmsg: always send credentials 
If the caller doesn't specify ancillary data, add credentials to the
outgoing packet.

This enables us to satisfy the requirement
(https://man7.org/linux/man-pages/man7/unix.7.html) that a socket with
the SO_PASSCRED option enabled can get the credentials of its peer in
every message it receives.

FIXME: I'm not sure if this is the right way to satisfy that
requirement.  A possible alternative would be to arrange for a socket
to be notified when its peer enables SO_PASSCRED.
