watchman: drop some py2 compat code

The `unicode` reference was being flagged by pytype, even though it was never
evaluated on py3.  There's more that can be dropped and `compat.py` can probably
be inlined if we don't care about minimizing the code changes from FB.  But I
don't feel like dealing with that.

#!/usr/bin/env python3


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)
