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.

```

Check same result using `experimental.extra-filter-revs`

  $ hg -R test --config experimental.extra-filter-revs='not public()' serve -p $HGPORT1 -d --pid-file=hg2.pid -E errors.log
  $ cat hg2.pid >> $DAEMON_PIDS
  $ hg -R test2 incoming http://foo:xyzzy@localhost:$HGPORT1/

  $ cat errors.log
  $ killdaemons.py

Check the behavior is other filtered revision exists
----------------------------------------------------

add more content and complexity to the repository too

  $ hg -R test debugbuilddag '+6:branchpoint.:left+4*branchpoint.:right+5' --from-existing
  $ hg -R test phase --public 'desc("re:^r11$")'
  $ hg -R test phase --secret --force 'desc("re:^r9$")'
  $ hg -R test log -G -T '{desc} {phase}\n'
