In SERVER-50401, we added a call to evergreen to help determine what commit we need to compare against in order to determine what files changed. However, when run on a local machine, the evergreen call is not made. It would be nice if the evergreen.py dependency did not need to be install when running in local mode.

As a server engineer,
I don't want local lint to require installing evergreen.py
So that I can run the command without having to install that requirement.

AC:

• lint can be run locally without having the evergreen.py library installed.
