adhoc-revtuple-generator: Explicitly specify refs to fetch

Some of the git trees in $c{Repos} may have been created (eg by
earlier versions of git or earlier versions of osstest) without the
usual
  remote.origin.fetch = +refs/heads/*:refs/remotes/origin/*
git config setting.

Pass this refspec explicitly, instead of relying on it being set as
the default.

Amongst other things, this will prevent a possible error during
bisection
  git fetch -p origin
  [stuff]
  fatal: bad object 3e3d5f6146c3f684f4b7bd71feffc31e1c668754
which is currently appearing in our cron mail.
