Conda jobs failing with numpy run_exports issue

The lal:conda:fftw job is failing with

  ERROR (python-lal): run-exports library package conda-forge::numpy-1.19.5-py37h3e96413_3 in requirements/run but it is not used (i.e. it is overdepending or perhaps statically linked? If that is what you want then add it to `build/ignore_run_exports`)

This is because https://github.com/conda-forge/numpy-feedstock/commit/bca09161e46d1a986e061e4aaf6a21d8eb809a98 added a run_exports to the numpy recipe that causes our pedantic build to fall over.
