try harder to find genhdlist2 on CPAN testers

rationale:
in some cases, all dependency modules and scripts still reside in the
uninstalled blib directories.
CPAN.pm knows how to deal with uninstalled modules (all the blib/lib
directories go into the PERL5LIB environment variable).
But it does not do something similar for the blib/script directories.

So we have to try harder to find genhdlist2 by adding those blib/script
directories to PATH if they exist
