egl/wayland: Don't block on EGL_DEFAULT_DISPAY under wayland

Normally the application will own the main event queue and be responsible
for moving events.  In case of EGL_DEFAULT_DISPLAY, EGL opens the display
and has to own the main queue so it can move the events itself.
Call wl_display_dispatch_pending() to take ownership.
