SSL test programs: prepare to unify common code

In preparation for unifying the common RNG-related code of ssl_client2
and ssl_server2, make it possible to copy-paste that code out of these
programs' main() functions:

* Replaces reads of the non-unifiable structure opt by reads of a
  separate variable.
* Replace references to the local variable rng by a pointer.
