sci-libs/suitesparse: new version 5.4.0.

All of the individual suitesparse components have been updated, but I
didn't realize there was a metapackage. And the 4.x versions of the
metapackage have incorrect dependencies that are trying to pull in the
components that belong to suitesparse-5.4.0. This is producing some
confusing errors. This commit adds a new version of the metapackage
with correct dependencies (tied to the versions of the components that
ship with suitesparse-5.4.0), and should let ~arch users upgrade
everything after switching from USE=metis to USE=partition. At some
later point, we can prune the 4.x metapackage and components and be
dont with that.
