Use strlcpy when copying node IDs into measured_bw_line_t
We were using strncpy before, which isn't our style for stuff like this.
This isn't a bug, though: before calling strncpy, we were checking that strlen(src) was indeed == HEX_DIGEST_LEN, which is less than sizeof(dst), so there was no way we could fail to NUL-terminate. Still, strncpy(a,b,sizeof(a)) is an idiom that we ought to squash everyplace.
