  Make test_compileall more robust by using -S to keep sys.path minimized.

  Try this again, hopefully the right way this time.

  Arfrever Taifersar Arahesis reported that test_compileall failed during Gentoo
  install because it was tyring to write .pyc files to a read-only system
  directory during test_no_args_compiles_path.  Having the tests call python
  with -S should eliminate the system directories from the path.
