Fix: wildcard excludes in unarchive with tar archives (#40935)

* fix: exclude using wildcards for tar archives

Fixes #37842, #22947

* fix: Remove quote() as it munges the exclude format

* test: Refactor to use single archive structure

A common structure archived by different methods should simplify some of
the feature tests.

* test: Use common archive layout to validate exclude feature

* test: Use the same exclude checks for zip/tar archives
