Cherry-pick #19604 to 7.x: [Filebeat] [tests] Keep host.name in forwarded events

[adriansr]

Cherry-pick of PR #19604 to 7.x branch. Original message:

What does this PR do?

Updates Filebeat's test_modules.py integration test to not strip the host.name field in events tagged as forwarded.

Why is it important?

So the -expected.json golden files keep the host.name field and errors in modules that populate this field can be detected.
