curl-openssl.m4: Fix version check for OpenSSL 1.1.1

Browse Source 
- Add OpenSSL 1.1.1 to the header/library version lists.

- Detect OpenSSL 1.1.1 library using its function ERR_clear_last_mark,
  which was added in that version.

Prior to this change an erroneous header/library mismatch was caused by
lack of OpenSSL 1.1.1 detection. I tested using openssl-1.1.1-pre1.
