demandimport: don't delay threading import

A recent cpython change breaks demandimport by importing threading
locally in importlib.util.LazyLoader.exec_module; add it (plus warnings
and _weakrefset, which are imported by threading) to demandimport's
ignore list.

```

For debugging: this is a pretty simple test that is a good candidate
for tracking down network-related bugs. Sometimes a command in this
hangs, so having showstack pre-loaded is sometimes helpful. This also
gives us a test that at least proves showstack can be loaded.
  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > showstack = $TESTDIR/../contrib/showstack.py
  > EOF
