Propagate HOME environment variable to unittests. This is necessary
to fix test failures resulting from pw_home pointing to a non-existing
directory while being overriden with HOME. Apparently Gentoo users
hit this sometimes when they override build directory for Portage.

Many editors and Python-related diagnostics tools such as
debuggers break or fail in mysterious ways when python files
don't end in .py. This is especially true on Windows, but
still exists on other platforms. I don't want to be too heavy
handed in changing everything across the board, but I do want
to at least *allow* lit configs to have .py extensions. This
patch makes the discovery process first look for a config file
with a .py extension, and if one is not found, then looks for
a config file using the old method. So for existing users, there
should be no functional change.
