test/openssl/test_config: skip tests for .include on older OpenSSL

The .include directive was initially added by OpenSSL 1.1.1, but the
syntax was later modified in 1.1.1b to improve compatibility with the
parser in <= 1.1.0. The test case expects 1.1.1b's parser.

The test case is failing on Ubuntu 18.04 because it still uses the
initial 1.1.1 release:
