derivations: Move grafts to (guix grafts). 

* guix/derivations.scm (<graft>, graft-derivation, %graft?)
(set-grafting): Move to...
* guix/grafts.scm: ... here.  New file.
* guix/gexp.scm, guix/packages.scm, tests/packages.scm,
guix/scripts/build.scm: Use it.
* Makefile.am (MODULES): Add it.
(SCM_TESTS): Add tests/grafts.scm.
* tests/derivations.scm ("graft-derivation"): Move to...
* tests/grafts.scm: ... here.  New file.
