catkin_virtualenv

* Correct dependencies and autoformat (#72 <https://github.com/locusrobotics/catkin_virtualenv/issues/72>)
  * Remove python-virtualenv dep
  * Add python2-dev
  * Lint
* We're ok with any 44.x version of setuptools (#71 <https://github.com/locusrobotics/catkin_virtualenv/issues/71>)
  But not anything newer.
  Older versions don't appear to work reliably with pip==20.1.
  This helps when running a build of a package depending on catkin_virtualenv on OS which ship with an old version of setuptools (such as Ubuntu Xenial) when USE_SYSTEM_PACKAGES is not set to FALSE. In that situation, only specifying 'setuptools<45` will be true, as setuptools is installed (in the systems site packages), so pip will not upgrade it. Specifying a minimum version like this will force pip to always install an up-to-date version.
