test-import: remove unneeded chmod call

As pointed out by Mads, setting the x bit on dummypatch.py is unneeded, because
it is called with 'python ../dummypatch.py'.

#!/usr/bin/env python

import errno, os, sys

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

sys.exit(0)
