libinterimap: use default locations for trusted CA certificates when neither CAfile nor CApath are set.
In particular, OpenSSL's default locations can be overridden by the SSL_CERT_FILE resp. SSL_CERT_DIR environment variables, see SSL_CTX_load_verify_locations(3ssl). This bumps the minimum OpenSSL version to 1.1.0 (when SSL_verify is used).
