Subject: [PATCH 3/4] Ignore libblas/liblapack run_exports to fix version
 solver preference

The auto-generated run_exports from libblas/liblapack in host
(e.g. >=3.11.0,<4.0a0) forced the solver to use newer MKL from
conda-forge, making simcoon 1.10.x harder to install than 1.9.6
when Python was installed from the defaults channel.

By ignoring these run_exports, the explicit run dependencies
(libblas * *mkl, etc.) still correctly pin the BLAS backend
without unnecessarily constraining the version.
