Use appendStringInfoString instead of appendBinaryStringInfo where possible

For the jsonpath output, we don't need to squeeze out every bit of
performance, so instead use a more robust coding style.  There are
similar calls in jsonb.c, which we leave alone here since there is
indeed a performance impact for bulk exports.
