xwayland: "EGL_EXT_device_base" required for EGLStream

Browse source 
eglQueryDevicesEXT() would abort if the required extensions are not
available, meaning that enabling “-eglstream” on a non-EGLStream
capable hardware would lead to an abort().

Check that "EGL_EXT_device_base" extension is available and bail out
early if not, so we don't abort() later in eglQueryDevicesEXT().
