WINGs/wclient_wl: create RContext before WMCreateScreenWithRContext 

wlclient_open passed NULL as the RContext, causing a segfault in
RConvertImageMask (called from makePixmap during screen init) when
WPrefs.app launched under Wayland.

Fix: call RCreateContextWayland() to create a valid 32-bit ARGB
context before passing it to WMCreateScreenWithRContext.
