android: Wait on fences in CameraStream::process()

Acquire fences for streams of type Mapped generated by
post-processing are not correctly handled and are currently
ignored by the camera HAL.

Fix this by adding CameraStream::waitFence(), executed before
starting the post-processing in CameraStream::process().

The change applies to all streams generated by post-processing (Mapped
and Internal) but currently acquire fences of Internal streams are
handled by the camera worker. Postpone that to post-processing time by
passing -1 to the Worker for Internal streams.

Also correct the release_fence handling for failed captures, as the
framework requires the release fences to be set to the acquire fence
value if the acquire fence has not been waited on.
