Python 3 support, second attempt (Trac #9184)

Summary:
This is a fixup of https://phabricator.haskell.org/D233

The only difference is in findTFiles (first commit), which
previously broke Windows runner; now I translated literally
instead attempting to improve it, and checked it works.

Test Plan:
I used validate under 2,3 on Linux and under 2 on msys2.
On Windows I've seen a large number of failures, but they don't
seem to be connected with the patch.
