Some constraints files[1] contain valid data but we want to ignore them
when generating a combined lower-constraints.txt, rather than erroring
out:
[tony@thor requirements]$ time .tox/venv/bin/build-lower-constraints ../*/lower-constraints.txt > tjmaxx.txt
Traceback (most recent call last):

raise ValueError('could not find version for {}'.format(req))
ValueError: could not find version for Requirement(package='', location='', specifiers='', markers='', comment='# flake8==2.5.5', extras=frozenset())
Let's just ignore comments in those files.
