[PATCH v11 13/19] lc-compliance: Move camera setup to CameraHolder class

[Sven Püschel]

From: Nícolas F. R. A. Prado <nfraprado at collabora.com>

Different base classes can be used for different setups on tests, but
all of them will need to setup the camera for the test. To reuse that
code, move it to a separate CameraHolder class that is inherited by test
classes.
