List system dependencies for running common tests

Add an other-requirements.txt file containing a cross-platform list
of dependencies needed for running included tox-based tests. Also
include a tox environment for convenience calling the bindep[*]
utility to list any missing system requirements.

This change is needed since the infra team will not install standard
packages in jobs anymore, projects should use other-requirements.txt
instead. The macros xvfb-install, firefox-install, chrome-install
which are used to run some jobs for this repository will be removed
soon.

This change is self-testing.
