lib: string: Implement strlcat
This introduces strlcat, which provides a safer interface than strncat. It
never copies more than its size bytes, including the terminating nul. In
addition, it never reads past dest[size - 1], even if dest is not
nul-terminated.
This also removes the stub for dwc3 now that we have a proper
implementation.
