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.
