derivations: Keep the .drv file name in <derivation> objects. 

* guix/derivations.scm (<derivation>): Add 'file-name' field.
  (%read-derivation): Use (port-filename DRV-PORT) as the file name for
  the result.
  (derivation): Set the 'file-name' field in the result.
* tests/derivations.scm ("build derivation with 1 source"): Assert that
  'derivation-file-name' returns the right thing.
