[cgiapp] CGI::Application:Dispatch 3.0 test failures

[Mark Stosberg]

The new CGI::Application::Dispatch 3.0 release is failing some
PSGI-related tests on most-but-not-all platforms:

http://www.cpantesters.org/distro/C/CGI-Application-Dispatch.html#CGI-Application-Dispatch-3.00

Help would be welcome looking into those. I'll try to get to them in the
next 48 hours if someone else doesn't get to them first.
