packages: Call 'bag-grafts' only on the tip of the package graph.
This reinstates pre-gexp behavior where 'expand-input' would explicitly pass #:graft? #f in recursive calls, thereby preventing redundant calls to 'bag-grafts'. * guix/packages.scm (expand-input): Turn into a monadic procedure. Lower INPUT when it's a package, passing #:graft? #f. (bag->derivation, bag->cross-derivation): Adjust accordingly. * tests/packages.scm ("search paths"): Adjust so BUILD aborts only when passed the package of interest.
