Revert "Add OPENSSL_VERSION_AT_LEAST" 



Fixes #5961

This reverts commit d8adfdcd.

The macros OPENSSL_MAKE_VERSION() and OPENSSL_VERSION_AT_LEAST() contain
errors and don't work as designed. Apart from that, their introduction
should be held back until a decision has been mad about the future
versioning scheme.

OPENSSL_VERSION_AT_LEAST(major,minor) can be

used in C<#if> statements in order to determine which version of the library is

being used. This can be used to either enable optional features at compile
