math/suitesparse: simplify

- Allow using Clang again (base libomp.so or OpenMP disabled)
- Respect C++ library if using GCC (must be libc++ on Clang architectures)
- Respect CFLAGS/CXXFLAGS in subdirectories using CMake
- Respect BLAS/LAPACK choice (actually use OpenBLAS)
- Enable Intel threading building blocks support
- Switch to vendor build/install targets
- Adjust plist for new items (GraphBLAS, Mongoose, DOCS)
- Skip running demos during build
