[PATCH] buildhistory: use bb.utils.mkdirhier instead of os.makedirs

[Martin Jansa <martin.jansa@gmail.com>]

From: Martin Jansa <martin.jansa@gmail.com>

* Multiple do_fetch[prefunc] can happen at the same time and
  if not os.path.exists(pkghistdir):
    os.makedirs(pkghistdir)
  isn't safe
* Use bb.utils.mkdirhier which doesn't raise error when directory exists
