benchtests: Fixed bench-memcpy-random: buf1: mprotect failed

This patch fixed mprotect system call failure on AArch64.
This failure happened on not only A64FX but also ThunderX2.

Also this patch updated a JSON key from "max-size" to "length" so that
'plot_strings.py' can process 'bench-memcpy-random.out'
