server: Allow absolute paths in WAYLAND_DISPLAY

The compositor should handle absolute paths in WAYLAND_DISPLAY like the clients, ie not
adding the XDG_RUNTIME_DIR prefix if it's an absolute path.

This allows to create the wayland socket in a separate directory for system compositors if
desired. Clients could then directly inherit the environment variable.
