lapack, blas: added dummy blas package pulling in lapack

As the new lapack package provides both libblas.so and liblapack.so,
mirroring optimized BLAS offerings, a dummy blas package is maybe useful
to replace the existing math/blas. This keeps packages working that still
directly use math/blas instead of mk/blas.buildlink3.mk, and also any
bulk build scripts that have it in a list of packages to build.

Note that the upgrade from installed math/blas and math/lapack does
not work without you removing the old installs first. Pkgsrc cannot
automatically handle this type of conflict yet.
