[FEATURE] Compatibility with Amazon Linux 2

[OneBadSanta]

Is your feature request related to a problem?

I am unable to use this formula due to incompatibility with Amazon Linux 2. The splunk user and group do not get created and loggroup does not exist.

Additional context

This is the output from a highstate
