build-system/gnu: Optimize the package graph. 

With this change, the output of:

  guix graph -e '(@@ (gnu packages commencement) coreutils-final)' |grep 'label = ' | wc -l

drops from 76 nodes to 68 nodes, and the "add-data-to-store-cache" hit
rate for:

  guix build libreoffice -d --no-grafts

drops from 3.9% to 2.6%.

* guix/build-system/gnu.scm (package-with-explicit-inputs*)[cut?]:
Adjust condition to exclude packages with build systems other than
GNU-BUILD-SYSTEM, such as 'ld-wrapper-boot3'.
