Change the default of tls-use-system-policy-versions at build-time

Browse Source 
Allow simple switch to change default of that option. Use it on Red Hat
builds where we want crypto-policy to be a primary source of such
configuration. Of course keep ability to disable that or reconfigure
explicit TLS settings.

Subject: [PATCH] Add a new build-time option for system TLS
We want to use crypto-policy provided configuration always in our
builds. Allow changing the default of tls-use-system-policy-versions at
build time by a simple configure parameter.
