Added a fix for timestamp field mapping as well for the github package to get the CI to pass, they are usually added to base-fields.yml rather than ecs.yml for now.

The format used to check if add_host_metadata processor should run or not, for some packages, was wrong

It doesn't affect add_host_metadata. It looks like it affects whether publisher_pipeline.disable_host: true is added.

[andrewkroh]

This would be preferred, but it's not supported because of elastic/elastic-package#749.
