Process status-fd completely before finishing dpkg call

Exiting the processing loop as soon as the dpkg process finishes might
leave status-fd lines unprocessed which wasn't much of a problem in the
past as the progress would just be slightly off, but now that we us the
information also for skipping already done tasks and generate warnings
if we didn't see all expected messages we should make sure we seem them
all. We still need to exit "early" if dpkg exited unsuccessfully/crashed
through as the (remaining) status lines we get could be incomplete.
