Update openssl-devel dependency in RPM spec.

Since openssh 9.4p1, openssl >= 1.1.1 is required, so
build with --without-openssl elsewhere.
According to https://repology.org/project/openssl/versions
openssl 1.1.1 is available on fedora >= 29 and rhel >= 8.
Successfully build tested, installed and run on rhel 6
