update_engine: Implement SOURCE_COPY/SOURCE_BSDIFF operations.
Implement SOURCE_COPY and SOURCE_BSDIFF in DeltaPerformer. These new
operations are the same as MOVE and BSDIFF, respectively, except
that they read from the source partition rather than the destination
partition.
Also fills in the source paths in omaha_response_handler_action, which
were previously not being set.
