[bug#39839] [PATCH] gnu: suitesparse: Update to 5.7.1

[Felix Gruber]

* gnu/packages/math.scm (suitesparse): Update to 5.7.1
[source]: The latest releases of SuiteSparse have only been published on
GitHub. Fetch from git tag as GitHub releases page only contains
autogenerated tarballs that guix lint complains about.
[patches]: add patch for Mongoose's CMakeList.txt to find
SuiteSparse_config.
[arguments]: Add cmake flags used by new components GraphBLAS and
Mongoose.
[native-inputs]: add cmake and m4 needed to build GraphBLAS and Mongoose.
