[Cbc] Package management LAPACK/BLAS dependency update?

[Miles Lubin]

Hi Matthew,

It appears that you're correct. The build on Debian's servers does not pick
up LAPACK and BLAS for some reason, so they're not included as
dependencies. If you notice any performance differences I can make this a
priority to fix, but it's unlikely because Clp only uses LAPACK for very
dense problems (and because the default LAPACK in Debian isn't very fast
anyway).

Best,
Miles
