tools/nolibc: Fix strlcat() return code and size usage

The return code should always be strlen(src) + strnlen(dst, size).

Let's make sure to copy at most size-1 bytes from src and null-terminate
the dst buffer if we did copied something.

While we can use strnlen() and strncpy() to implement strlcat(), this is
simple enough and results in shorter code when compiled.
