run-tests: alias hg to hg.exe on Windows

To enable legacy stdio mode on Windows, hg.exe needs to be updated.  But before
that, we actually have to use it when running the tests.  I *think* what was
happening before was when MSYS invoked `hg`, it looked at the shbang line and
ran python.exe found there.  The test harness must be updating $PATH to include
the python used to launch it, and therefore it ran py3.  As a side note, this
also fixed `py -3 run-tests.py` (without --local), which complained about the
space in the shbang line before this.

This should also help in WSL, because the explicit '.exe' is needed to invoke a
Windows app instead of invoking the Linux app.

I have no idea why this change capitalizes Lib in the tests, as it was
previously lowercase for both py2 and py3.
