Fix entirely skipped enforcer in infinispan-client IT and resolve violations

This skipped way too many checks:

...and (as expected) the minimal deployment dependencies were missing as well.

I don't think the exclusions I added have actually changed the relevant semantics. Everything is still passing.
But then again: I'm not an Infinispan expert and I'm not sure what this "jboss marshalling" comment was about.

Note: This is already handled in IT parent. With this change, the native IT ran just fine in my fork.
