tests: Further factorize substitute mocks. 

* guix/tests.scm (derivation-narinfo): Turn 'nar' into a keyword
  parameter.  Add #:sha256 parameter, and honor it.
  (call-with-derivation-narinfo): Add #:sha256 and pass it to
  'derivation-narinfo'.
  (with-derivation-narinfo): Extend with support for (sha256 => value).
* tests/store.scm ("substitute query"): Use 'with-derivation-narinfo'.
  ("substitute"): Likewise.
  ("substitute, corrupt output hash"): Likewise.
  ("substitute --fallback"): Likewise.
* tests/derivations.scm: Remove Emacs local variable.
