Simon Gomizelj fa54884131 Fix unit tests when run with PYTHONDONTWRITEBYTECODE
When set, it will conflict with any tests that generate bytecode
because they don't expect it to be set.

Fixable by sanitize the environment before forking, but we can't do
anything about import tests.

This is a pipenv default, and possibly a sane flag to set while doing
Hy development, so lets not let it be a hazard for developers to trip
over.
