packages: 'package-transitive-supported-systems' accounts for implicit inputs.
Reported by Federico Beffa.

* guix/packages.scm (package-transitive-supported-systems): Use
  bag-direct-inputs + package->bag rather than package-direct-inputs.
* tests/packages.scm ("package-transitive-supported-systems"): Add
  explicit 'build-system' field to each 'dummy-package' form.
  ("package-transitive-supported-systems, implicit inputs"): New test.
