[9.3](backport #49529) Fix the globs for collecting artifacts from failed tests

[mergify]

Proposed commit message

Ensure everything on the following folders are always collected by
BuildKite after the tests.
 - filebeat/build/input-test
 - filebeat/build/integration-tests
 - x-pack/filebeat/build/input-test
 - x-pack/filebeat/build/integration-tests

Those folders contain the state of failed tests, which is very helpful
to investigate failing and flaky tests.
