grafts: Create only one grafted variant of each derivation.
Currently, with several grafts applicable to Inkscape, this makes:
guix gc -R $(guix build inkscape -d) | wc -l
go from 2376 to 2266 (4.6%).
* guix/grafts.scm (cumulative-grafts): Pass 'graft-derivation/shallow'
the subset of GRAFTS that applies to DRV.
