Update devserver urls with /archive in autotest(2)

[autotest] Remove archive from the devserver url patterns.
Devserver is removing static/archive so that everything is served
straight from the static directory. Cutting out calls in autotest to
match.

BUG=chromium:214373
TEST=Ran a suite with a reimage job on a DUT with the old
     style job_repo_url.
