Disable Starlark implementation of py_library for unsupported cases.

 * Most of this is due to Python 2 support (which is being dropped as part of
   the Starlark rewrite).
 * Also disables the Starlark impl for tests of the `imports` attribute
   (this is disabled within Google, and not yet implemented).

Work towards #15897
