[issue19700] Update runpy for PEP 451

[Nick Coghlan]

Nick Coghlan added the comment:

Latest version simply doesn't check the loader type for the zipimport tests. (Note that just using find_spec doesn't work, since the directory and zipfile execution tests include implicit sys.path manipulation)

I also removed the separated "precompiled" flag that was in earlier patches, since importlib.util.spec_from_file_location deals with that for us.

If the full regression test suite passes, I'll be checking this version in.
