mail-mta/postfix: backport fix for too eager warning

do not log a warning for minor version changes for openssl >= 3.0.0. The
overall warning logic is:

	when the OpenSSL library compile-time version
	differs from the run-time version, allow forward-compatible
	minor version differences with OpenSSL >= 3.x.x, allow
	forward-compatible micro version differences with OpenSSL
	1.1.x, and allow no version difference with OpenSSL <=
	1.0.x. Otherwise, log a potential version mismatch warning
