Subject: [PATCH] wayland: Do not fail on stalled .X11-unix entries

If for whatever reason, there are stalled files in /tmp/.X11-unix/ the

bind() to the abstract socket will succeed but not the bind() to the

to the UNIX socket.

This causes gnome-shell/mutter to fail because it cannot start Xwayland

(while it could actually, by using a different display).

In case of failure to bind to the UNIX socket, try the next display

instead of failing, to avoid stalled entries in /tmp/.X11-unix.

Closes: https://gitlab.gnome.org/GNOME/mutter/issues/13
