py3: allow run-tests.py to run on Windows
This is now functional:
HGMODULEPOLICY=py py -3 run-tests.py --local test-help.t --pure --view bcompare
However, on this machine without a C compiler, it tries to load cext anyway, and
blows up. I haven't looked into why, other than to see that it does set the
environment variable. When the test exits though, I see it can't find
killdaemons.py, get-with-headers.py, etc.
I have no idea why these changes are needed, given that it runs on Linux. But
os.system() is insisting that it take a str, and subprocess.Popen() blows up
without str:
Errored test-help.t: Traceback (most recent call last):

needquote = (" " in arg) or ("\t" in arg) or not arg
TypeError: argument of type 'int' is not iterable
This is exactly how it crashes when trying to spin up a pager too. I left one
instance of os.system() unchanged in _installhg(), because it doesn't get there.
