Test failures when building Portable package

[shawnlaffan]

Originally reported at StrawberryPerl/Perl-Dist-Strawberry#300

The Portable build has test failures on one of my machines but not on another machine on the same network. These have also surfaced for some cpan-testers machines (e.g. https://matrix.perl-magpie.org/results/25d42f9f-7d9b-1014-9dcb-8e4de8b45353 ).

The target URL has a redirect, so this might be a consequence of recent network changes on the servers.

If this is a connectivity issue then the test should perhaps be modified to skip when this error occurs. FWIW, all tests are skipped when the machine is offline.
