Refine the library linking for the tests of DnsResolver

Some MTS tests failed due to libbase becoming incompatible between Q and R.
Refine the linking for our tests to fix the problem and prevent similar issues.
1. liblog has stable C APIs so just have it linked shared.
2. Statically link all libraries as we can.
