Lower down corpus backup public marking time (#1889)

Change corpus backup public marking time from 90 to 30 days.

Now that we archive crash regressions in corpus backup, it makes sense for projects to use this corpus backup sooner than later. Also, anyone can generate this corpus with enough cpus, so 30 days seems reasonable.
