From: Paul Eggleton <paul.eggleton@linux.intel.com>

* Check if BUILDHISTORY_DIR exists before doing anything with it, in
  case no tasks that would have created it have executed
* Ensure the git repo in BUILDHISTORY_DIR is initialised with "git init"
  before attempting to do anything with it
* Check if any files have been added or changed before adding and
  committing, to avoid an error from "git commit"
