package/clapack: remove package

clapack has been unmaintained for a couple of years. It is
semi-automatically generated from lapack sources using the f2c
fortran-to-C converter, which itself is pretty much unmaintained.

Remove the package. Remove the dependency on !CLAPACK from lapack.
Automatically select lapack from legacy if possible.
