t5001: add tests for export-ignore attributes and exclude pathspecs

Demonstrate mishandling of the attribute export-ignore by git archive
when used together with pathspecs.  Wildcard pathspecs can even cause it
to abort.  And a directory excluded without a wildcard is still included
as an empty folder in the archive.
