Use centos6 ssl detection for other recent centos versions.

The most recent Centos versions, 7 and 8, have the same issue as
centos 6, the ssl backend is not automatically detected through
conventional ways.

So the detection of the ssl backend on Centos 6, should be used for
recent Centos versions as well.
