Subject: derivations: Simplify 'substitution-oracle'.

* guix/derivations.scm (substitution-oracle)[valid?, dependencies]:
Remove.
[closure]: New procedure.
Rename parameter from 'drv' to 'inputs-or-drv' and adjust accordingly.
(derivation-build-plan): Pass INPUTS directly to 'substitution-oracle'.
* guix/ui.scm (show-what-to-build)[substitutable-info]: Likewise.
