[PATCH weston 1/3] gl-renderer: fix EGL initialization steps

From: Manuel Bachmann <manuel.bachmann at open.eurogiciel.org>

Some DRI drivers, including VMware vmwgfx, do not support
calling eglQueryString() with a EGL_NO_DISPLAY parameter.
Just as we do in gl_renderer_supports(), which returns 0
but does not fail in this case, do not fail in
