Fix false negatives in integration test for unused vars

Updated tests/integration/test_vars_usage_in_yaml.py:
- Variables immediately followed by '(' are now treated as function calls,
  not as set variables. This prevents false errors.
- Fixed detection of redirect_domain_mappings so it is no longer flagged
  as unused.
