Niklas Söderlund 0085202fe2 test: v4l2_device: Switch most tests to vimc
The vimc driver delivers frames much faster then the vivid driver hence
most v4l2 device tests complete much quicker if vimc is used. The only
v4l2 device test which can't be switched is buffer_sharing as it needs
to import buffers somewhere, something vimc do not support.

With this change I manage to shave of almost 7 seconds for each run of
all v4l2 device tests.
