SuiteSparse: update to v1.7.0 (still 5.4.0) (#650)

Add SuiteSparse v1.7.0 release:
https://github.com/jlblancoc/suitesparse-metis-for-windows/releases/tag/v1.7.0

A new variable `SuiteSparse_METIS_VERSION` is provided, which will be
useful when `ceres-solver v2.2.0` comes out.

And the generated cmake-config file is fixed, it always assumed to be
built with `WITH_OPENBLAS` because of a missing `@` for substitution.
