Bug#29994326 REMOVE HAVE_SSL.INC AND HAVE_OPENSSL.INC FROM THE TESTSUITE

It is no longer possible to compile the server without SSL
support. Also, going forward in 8.0, we only support OpenSSL.

Hence it makes no sense for tests to skip if SSL support is not
present or to try and determine if we are running with OpenSSL or not.

This patch removes the relevant include files (have_ssl.inc,
have_openssl.inc, not_openssl.inc) from the source and adjusts the
tests as necessary.

   @page PAGE_INCLUDE_FILES Using Include Files to Simplify Test Cases
 
   The <b>include</b> directory contains many files intended for
-  inclusion into test case files. For example, if a test case needs to
-  verify that the server supports <b>SSL</b> connections, use this

   These include files serve many purposes, but in general, they
   encapsulate operations of varying complexity into single files so
