[11.0.X] Use OpenBlas instead of GSL Blas implementation

[cmsbuild]

backport of #5540

Resolves #5528

Drop unused specs

• photospline
• suitesparse

and to make sure that we do not use lapack blas implementation we propose to drop it in favor of openblas.

Move gslcblas library in to separate directory so that no one can link against it.
