bpo-34783: Disable test_nonexisting_script for macOS framework builds (pythonGH-9831)

With macOS framework builds, test case test_nonexisting_script in test_nonexisting_script fails because the test case assumes that the file name in sys.executable will appear in the error message. For macOS framework builds, sys.executable is the file name of the stub launcher and its file name bears no relationship to the file name of the actual python executable. For now, skip the test in this case.
