packages: 'package-transitive-supported-systems' detects cycles.
With this change, commands such as 'guix build' or 'guix package' report
obvious package-level cycles upfront. Derivation-level cycles are not
detected.
* guix/packages.scm (&package-cyclic-dependency-error): New condition
type.
(package-transitive-supported-systems): Define 'visited', check it, and
parameterize it.
* guix/ui.scm (call-with-error-handling): Handle
'&package-cyclic-dependency-error'.
* tests/packages.scm ("package-transitive-supported-systems detects
cycles"): Add test.
