Issue #26268: Update the prepare_ssl.py script

It can now handle OpenSSL versions 1.0.2e and greater, which don't
include include files in include/.

Note that sources prepared by this script no longer support the old
project files for 2.7; you now have to have Perl available to use
the old build_ssl.py script with sources from svn.python.org.
