py3: fix str vs bytes in enough places to run `hg version` on Windows

I don't have Visual Studio 2015 at home, but this now works with a handful of
extensions (blackbox, extdiff, patchbomb, phabricator and rebase, but not
evolve):

    $ HGMODULEPOLICY=py py -3 ../hg version

Enabling the evolve extension causes the usual "failed to import ..." line, but
then print this before the usual version output:

    ('commit', '[b'debugancestor', b'debugapplystreamclonebundle', ...,
     b'verify', b'version']')

... where the elided part seems to be every command and alias known.

#!/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)
