test: Extract CameraTest class out of camera tests to libtest

Many tests other than the camera/ tests use a camera. To increase code
sharing, move the base CameraTest class to the test library. The class
becomes a helper that doesn't inherit from Test anymore (to avoid
diamond inheritance issues when more such helpers will exist).
