tests: add a test for installing hg with pip in a virtualenv

Since we're doing so much clever junk in our setup.py, let's have a
test that exercises it.

Thanks to Matt Harbison for testing this on Windows and verifying that
installenv/*/hg would work as a way to work around bin being called
Scripts on Windows.
