packages: 'specification->package+output' distinguishes "no output specified".
Until now the caller couldn't tell the different between a spec like "foo:out" and one like "foo". This change allows users to distinguish between these two cases. * gnu/packages.scm (specification->package+output): Disable output membership test when OUTPUT = #f and SUB-DRV = #f. * tests/packages.scm ("specification->package+output") ("specification->package+output invalid output") ("specification->package+output no default output") ("specification->package+output invalid output, no default"): New tests.
