revsetlang: use sysbytes() instead of blind encode()

Otherwise we will call str.encode() on Python 2, which is wrong.

sysbytes() does encode('utf-8') on Python 3. But the source is
guaranteed ASCII, so it shouldn't matter.

With this change, `hg` now runs with `HGUNICODEPEDANTRY=1` set.
However, several tests are failing.
