dev-perl/File-Next: Remove POD dependency

Normally the dependent tests could be nuked, but the test
suite is dependent on various files for testing iteration
of files.

So the POD tests are replaced with no-op tests that simply
pass as fast as possible, so that the Pod testing can be nuked
and the dependencies can be reaped
