environment: For --ad-hoc, allow users to specify an output.
* guix/scripts/environment.scm (package+propagated-inputs): Add 'output' parameter. Use it in return value. (options/resolve-packages): Use 'append-map' instead of 'map'. For 'load' and 'expression', return all the outputs of the resulting package. For 'package', use 'specification->package+output' instead of 'specification->package'.
