chore(ci): Add transforms-metric_to_log transform dependency to sink-humio

Given that the humio metrics sink depends on the log_to_metric
transform.

Also fix Makefile to run humio integration tests. I couldn't find a good
way to use a wildcard for the module (like
"::humio::*::integration_tests") so I just did the logs submodule for
now. It seems like there are plans to add regex support for test
filters: rust-lang/rust#53278
