bind9 FTBFS in bionic, regression in updates

[Dimitri John Ledkov]

[Impact]

 * when building bind9 with openssl 1.1.1 it picks up a new feature and exposes symbols in shared libraries to support it
 * this is problematic, as abi symbols of the shared library are changed based on the build-time version of OpenSSL
 * in later releases bind9 configuration option were tweaked to prevent autodetection and enablement of the new feature. Similar fix was applied in disco and unstable

[Test Case]

 * add-apt-repository ppa:ci-train-ppa-service/3540
 * rebuild the package
 * it should complete the build successfully without any "missing symbols" reported

[Regression Potential]

 * We are rebuilding the binaries, however, the test suite passes correctly with both old and new openssl without regressions.
