renderer-native: Fall back to non-modifier GBM surfaces

Browse Source 
If we attempt GBM surface allocation with a set of modifiers but the
allocation fails, fall back to non-modifier allocations. This fixes
startup on Pineview-based Atom systems, where KMS provides us a set of
modifiers but the GBM implementation doesn't support modifier use.

Closes: https://gitlab.gnome.org/GNOME/mutter/issues/84
