report: Add video to the top of the testrun page

It looks great and makes the awesome video recording feature more
visible.
virtual-stb & service: Share timezone with Docker containers

Otherwise the time is incorrect.  I'm not certain whether this is a good
idea.  We should really be storing all timestamps as UTC and convert at
the edges via javascript or dynamically generated web-pages.  It still
leaves open the question of should we be sending a timezone to the test-
packs at all?

Also: perhaps a virtual-stb would want to have a different timezone.  This
needs to be solved before the first release of the service stuff as any
incompatible change there would be strictly forbidden.
