store: Add 'references*'.

* guix/store.scm (references*): New procedure.
* guix/profiles.scm (manifest-lookup-package)[references*]: Remove.
* guix/scripts/system.scm (references*): Remove.
* tests/gexp.scm ("gexp->file", "gexp->file + file-append")
("gexp->derivation", "gexp->derivation, cross-compilation")
("gexp->derivation, ungexp + ungexp-native")
("scheme-file", "text-file*", "mixed-text-file"): Remove 'references*'
instead of (store-lift references).
