android: Move buffer mapping to CameraStream

The destination buffer for the post-processing component is
currently first mapped in the CameraDevice class and then passed
to CameraStream which simply calls the post-processor interface.

Move the mapping to CameraStream::process() to tie the buffer
mapping to the lifetime of the CameraBuffer instance.
