(maint) Make spec tests pass on windows

Windows requires the current puppet collection to be specified in
the puppet_agent class, so that is refactored to be globally
specified in the `spec_helper_acceptance`. Additionally, logic and
mocking was added to specifiy default install paths for the VERSION
file for both linux and windows.
