Add test for rancher plist file sync (#77)

Currently the rancher setup step doesn't know to replace the rancher
plist file when it changes. This means `ih-setup upgrade` doesn't know
it needs to re-run rancher setup.

This PR adds the check for whether the plist file is out of sync to the
`test` function in rancher setup.
