tests: configuration: Add a test to cover 'unset regression.
The regression was introduced with a2b89a3319dc1d621c546855f578acae5baaf6da, and introduce a risk that 'unset leaks to serialized configuration files. * tests/services/configuration.scm (maybe-symbol): New type. (config-with-maybe-symbol): New configuration. ("symbol maybe value serialization, unspecified"): New test. Reported-by: Attila Lendvai <attila@lendvai.name>
