Add previous_got_revision and previous_got_revision_cp to output

As chrome browser infra works to improve CQ times, we would like to
easily glance at builds and see how many new commits were checked out.
Currently you have to open up bot_update stdout to see the previous
HEAD revision and go from there. Having this conveniently outputted
would be very convenient.

If the bot has previously checked out the repo, output which revision
and commit position were checked out.
