Default include_role results to empty list in linear strategy plugin

Browse source 
Fixes #18544.

When a loop is over an empty list, the result is set to

    {'skipped_reason': u'No items in the list', 'skipped': True, 'changed': False}

which means that accessing `hr._result['results']` throws a `KeyError`.
