Fix the issue where without_openssl is always set to 1.

[wuwx]

In Fedora systems, %{?rhel} is empty. In RHEL systems, %{?fedora} is empty. Therefore, the original code always sets without_openssl to 1.

I think it would be better to leave the default of without_openssl at 0 and only override it for known-bad versions

[wuwx]

i've set without_openssl back to 0, and check fedora and rhel defined now

That's committed and will be in OpenSSH 9.9, due in a few weeks
