Make Firefox nightly download more robust.

Make Firefox nightly download more robust.

The script will now only start complaining if we haven't been able to
download anything for days. The script will always touch the file if
the download is successful, so the modified time of the latest
downloaded time is the benchmark of how fresh our Firefox build is.
There can be many days between FF nightly release, sometimes weeks,
so we only care if we managed to download something and not which date
the build is from.

lgtm with a suggestion: now that you've already done some datetime stuff, maybe
you can build in some cleaning of all archives except the latest one as well? I
checked chromeperf58 and found 1.1GB of old firefox archives, which I assume
will grow indefinitely.

I'd suggest tracking this implementation in a crbug, so we can easily assign it
to someone else in an optimistic future.

I'll make a separate patch with archive cleaning then.
