SCons: Fix import clash between Godot and system modules
SCons: Fix import clash between Godot and system modules

See #24965 for details. `sys.path.insert` is hacky, but should work
relatively well for both Python 2 and Python 3. When we eventually
deprecate Python 2 support, we could look into using importlib.

Fixes #24965.
