sci-libs/cholmod: new version 3.0.13.

Update to EAPI=7 and fix the HOMEPAGE, SRC_URI, and LICENSE. This is
part of a larger SuiteSparse v5.4.0 upgrade thanks to François Bissey
whose sage-on-gentoo ebuilds I'm using. There's a newer release
(v5.7.1) of SuiteSparse, but v5.4.0 has seen more testing.

This new version also refactors the package's USE flags, because
USE=minimal was being used to control the installation of several
different modules that all do different things. It's much better for
users to have three individual flags that control those options.
Moreover, with USE=minimal, there was a conflict between the "minimal"
and "metis" flags; both would try to control the --with-partition
option. Finally, the "metis" USE flag was dropped in favor of the
name "partition".
