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