block/qapi: always report full_backing_filename
Always report full_backing_filename, even if it's the same as
backing_filename. In the next patch, full_backing_filename may be
omitted if it cannot be generated instead of allowing e.g. drive_query
to abort if it runs into this scenario.
The presence or absence of the "full" field becomes useful information.
