  -----------
  --print-summary hangs indefinitely due to infinite loop in Manager 
ancestor-directory walk

Reviewed by Aakash Jain.

The while loops that walk up to find an ancestor directory's stats
reassigned ancestor_dirname from os.path.dirname(dirname) instead of
os.path.dirname(ancestor_dirname), so once the immediate parent wasn't
in device_test_stats, the loop recomputed the same value forever
instead of continuing up the tree. This made --print-summary hang.
