First stab at the `derivation' primitive.

* guix/store.scm (%store-prefix): New parameter.
  (store-path?, derivation-path?): New procedures.

* guix/derivations.scm (write-derivation): Pass SOURCES through
  `object->string'.
  (compressed-hash, store-path, output-path, derivation): New
  procedures.

* tests/derivations.scm (%store): New global variable.
  ("derivation with no inputs"): New test.
