[smack] [avc] Allows Bidirectional Write for atService & atQmiLinker

On Linux kernel 4.14, atService and atQmiLinker requires write
permission to each other to ensure AVC functionality. Since these
two applications are both system framework apps, there is little risk
allowing them to communicate.

Adding such rules can now make AVC working.
