benchtests: Make memset benchmarks print json
Make the memset benchmarks (bench-memset and bench-memset-large) print their output in JSON so that they can be evaluated using the compare_strings.py script. * benchtests/bench-memset-large.c: Print output in JSON format. * benchtests/bench-memset.c: Likewise.
