IMPALA-14514: Handle serializing bytes in bin/run-workload.py

On python 3, when Impyla receives a result with a string that is
not valid UTF-8, it returns that as bytes. TPC-DS Q30 on scale 20
has a result that contains invalid UTF-8, so bin/run-workload.py
can fail while trying to dump this to JSON.

This modifies CustomJSONEncoder to handle serializing bytes by
converting it to a string with invalid unicode handled with
backslashes.

Testing:
 - Ran bin/run-workload.py against TPC-DS scale 20
