Fixes <http://bugs.gnu.org/22872>.
Reported by myglc2 <myglc2@gmail.com>.

* test-env.in: Define and export 'GUIX_BUILD_OPTIONS'.
* tests/guix-build.sh: When setting 'GUIX_BUILD_OPTIONS', make sure it
contains '--no-grafts'.
* tests/guix-package.sh: Likewise.
* tests/guix-daemon.sh: Add (%graft? #f) in Scheme snippets.
