spa: libcamera: use CameraConfiguration::orientation

Browse source 
libcamera commit cc65629b68d49d ("libcamera: camera: Introduce Orientation") [0]
introduced to the `CameraConfiguration::orientation` member to describe the
orientation of the image in the received memory buffers.

Then c65e40b8480ffb ("libcamera: Use CameraConfiguration::orientation") [1]
removed `CameraConfiguration::transform`, which broke the libcamera plugin.

Fix that by using the new `orientation` member.
