dev-perl/XML-Parser-Lite: Bump to version 0.721.0

- EAPI6
- Exclude possible network test unless DIST_TEST_OVERRIDE inlcudes "network".
  (Note: this test could have pulled in other dependencies to test it under a useflag, but doing
   so introduces a dependency cycle, because the test in question is to test for regressions in those
   things. Instead, this test will still be present if network testing is enabled, and will auto-activate
   if somebody happens to satisfy the dependencies)

Upstream:
- Packaging changes ( esp in regards to circular dependency tests )
