Make util/wrap.pl work better on VMS

Make util/wrap.pl work better on VMS

Perl's system() on VMS needs to have the command line properly fixed
up, even with arguments passed in list form.  We arrange that by
having util/wrap.pl use the same command line fixups as OpenSSL::Test.

As a consequence, util/wrap.pl needs to be generated, to easily pick
up data from configdata.pm.  This also removes yet another file
copying hack from the build file templates.
