py3: use pickle directly

pycompat.pickle abstracted over the different pickle modules in
Python 2 and 3. Now that we're Python 3 only, it is safe to use the
`pickle` module directly. So this commit does that.

As part of this we remove the rules from check-code.py that were
forbidden direct pickle module use.

We retain the `util.pickle` symbol for backwards compatibility, just
in case some extensions were using it.
