[PATCH] cmd/mem.c: use memmove in do_mem_cp()

There's no 'mv' shell command for handling overlapping src and dst regions, and there's no point introducing one, when we can just make the existing 'cp' command DTRT in all cases. memmove() should at most be a few instructions more then memcpy() (to detect the appropriate direction to do the copy)
