Test linting osh on helm-toolkit changes

Since most of the charts in both openstack-helm and
this repo use helm-toolkit, changes in helm-toolkit
have the possibility of impacting charts in the
openstack-helm repo and will not be caught in testing
here.

This change adds a conditional linter to lint the
charts in the openstack-helm repo if any changes
to helm-toolkit are made.
