PyAPI: re-enable the "bgl" module for headless builds
Instead of removing the `bgl` module, set all it's functions to stubs
so importing `bgl` or any of it's members doesn't raise an error.
This avoids problems for scripts that import bgl but don't call it's
functions when running in background mode.
