do_fetch is not an sstate task and there is no ".tgz" file, only a
siginfo file which is data about how the checksum is constructed and
for debugging of other sstate checksums. Pulling the downloads from a
download mirror would likely be just as successful as it would be if
do_fetch were an sstate task.
