test_hexdump: use memcpy instead of strncpy
New versions of gcc reasonably warn about the odd pattern of
strncpy(p, q, strlen(q));
which really doesn't make sense: the strncpy() ends up being just a slow
and odd way to write memcpy() in this case.
Apparently there was a patch for this floating around earlier, but it
got lost.
