build: align minimum build dependencies with ndn-cxx

 * Recommend gcc >= 7.4.0
 * Require clang >= 4.0, or Xcode >= 9.0 on macOS
 * Silence an ABI-related diagnostic message from gcc on armv7
 * Update Travis CI job matrix

- *
- * Usage:

- *     auto formatter = new boost::unit_test::output::multi_log_formatter; // same as already configured logger

- *
- *      boost::unit_test::unit_test_log.set_formatter(formatter);
- *
