grafts: Actually cache grafts during the derivation DAG traversal.
This fixes a regression introduced in d38bc9a9f6feefc465964531520fee5663a12f48 whereby the cache was effectively disabled. Reported by Thomas Danckaert <thomas.danckaert@gmail.com>. * guix/grafts.scm (with-cache): In the cache miss case, wrap body in 'mbegin'.
