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'.
