Subject: sci-libs/gsl: strip the cblas provider role.

  Computationally sci-libs/gsl as a cblas provider has no significant
  advantage over the reference implementation.  Providing sci-libs/gsl
  as a general cblas provider introduces possibility circular
  dependency.  sci-libs/gsl should rather be a cblas user than a
  provider.

Closes: https://bugs.gentoo.org/688742
