Since Intel's default openmp implementation is available in the same src tarball, we can just include it in the package. This means that `mkl` now "just works" without any environment variables, fragile setup-hooks, or forced propagation. Since the openmp implementation is only needed at runtime (and for test cases), users can substitute a different one if they prefer by exporting it with `LD_PRELOAD`, which is how Intel recommends handling this. If they do not do so, `libiomp.so` lives next to `libmkl_rt.so` and thus will be in the RPATH as a sane default. Since this still comes from the same src tarball, we can ship it without losing the fixed-output derivation; likewise, since Hydra is not building or caching these, shipping these proprietary packages costs no bandwidth for the nix community.
