tests: v4l2_videodevice: Set media bus and pixel formats for vimc

Most of the video device tests are based on vimc and Linux commit
85ab1aa1fac17bcd ("media: vimc: deb: fix default sink bayer format")
changes the default media bus format for the debayer subdevices. This
leads to a -EPIPE error when trying to use the raw capture video device
nodes.

Fix this by explicitly setting media bus and pixel formats to known good
values which works before and after the upstream change.
