derivations: 'substitution-oracle' now ignores sub-trees that are valid.
Before that, "guix build qt", when only qt itself is missing, would lead 'substitution-oracle' to call 'substitutable-paths' with 318 items. Now, this is down to 6 items, because it doesn't ask about prerequisites that are already valid. * guix/derivations.scm (substitution-oracle)[valid-input?, dependencies]: New procedures. Use 'dependencies' and remove call to 'remove'.
