give strncpy() an appropriate limit

This tells strncpy() to copy max_len bytes instead of strlen(src)
bytes, which will set bytes beyond strlen(src) with null bytes.

We really only need strlen(src) + 1, but for debugging it's
nice not to have a bunch of garbage in the destination buffer.

This fixes a test which err'd due to the lack of a terminating NULL
at the end of dest (do_strcpy is only used by unit tests).

BUG=none
TEST=make test
