store: 'requisites' now takes a list of store items. 
* guix/store.scm (fold-path): Change 'path' to 'paths' and adjust body
accordingly.
(requisites): Likewise.
* guix/scripts/environment.scm (inputs->requisites): Adjust
user accordingly.
* guix/scripts/size.scm (requisites*): Likewise.
* guix/scripts/gc.scm (guix-gc): Likewise.
