gl-renderer: fix pbuffer surface creation
When there's neither configless nor surfaceless EGL extension
(i.e. not a Mesa driver), Weston falls back to a dummy pbuffer surface.
Weston attempts to find for that surface an EGL config but uses a NULL
array of pixel formats. This fails with the following messages:
EGL_KHR_surfaceless_context unavailable. Trying PbufferSurface
Found an EGLConfig matching { pbf; } but it is not usable because
neither EGL_KHR_no_config_context nor EGL_MESA_configless_context
are supported by EGL.
failed to choose EGL config for PbufferSurface
EGL error state: EGL_SUCCESS (0x3000)
Failed to initialise the GL renderer;
