Kees Cook 9d63a62588 randstruct: Fix gcc-plugin performance mode to stay in group

commit 381fdb73d1e2a48244de7260550e453d1003bb8e upstream.

The performance mode of the gcc-plugin randstruct was shuffling struct
members outside of the cache-line groups. Limit the range to the
specified group indexes.
