configure: require at least OpenSSL 1.1.1 (LTS)

Commit f256487cd8f29f24036efa5d91a84a26b048861a bumped requirement to
1.1.0 for OPENSSL_init_ssl.

Bump this again to 1.1.1, because it was an LTS version. Although it has
no mainline support anymore, it still has paid/premium support. 1.1.0 has
no support at all.

Motivated for use of BIO_read_ex() for next commits.
