setup3k: use getattr instead of hasattr

Note that hasattr is fixed on Python 3, so this is more about being
concise and keeping check-code happy than actual correctness of code.

#!/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)
