mkl: init at 2019.0.117

This packags the Intel Math Kernel library on x86-64 platforms, which is a
dependency for many data science and machine learning packages.

Upstream, Intel provides proprietary binary RPMs with a permissive
redistribution license. These have been repackaged in both Debian and Anaconda,
so we are not the first distribution to redistribute.
