parsers: fix two leaks in index_ancestors

Both happy paths through this function leaked the returned list:

1) If the list was of size 0 or 1, it was retained an extra time and then
   returned.

2) If the list was passed to find_deepest, it was never released before
   exiting this function.

Both paths spotted by cpychecker.

for f in sys.argv[1:]:
    try:
        print f, '->', os.readlink(f)
    except OSError as err:
        if err.errno != errno.EINVAL:
            raise
        print f, 'not a symlink'

sys.exit(0)
