tests: raise a better error when patterns are wrongly formatted

It is fairly easy to make mistakes when merging conflict in the pattern file.
A common mistake is to forget adding an extra trailing comma changing the
length of the tuple.

We now detect such error and raise a better error message that helps to find
it.

#!/usr/bin/env python

from __future__ import absolute_import, print_function

import errno
import os
import sys

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

sys.exit(0)
