Add the -a option to git cvsimport to always import all commits.

Without this, I always got a "refs/heads/origin is an invalid SHA1"
error. From the git-cvsimport manual:

  -a
      Import all commits, including recent ones. cvsimport by
      default skips commits that have a timestamp less than 10
      minutes ago.
