EC: Fix isa library version (2.14.0 -> 2.16.0)
Commit 371d45d brought in ISA-L 2.16 support for
Erasure Coding, however missed updating the isa lib
version.  This patch updates the version.

EC: Add AVX512 support for ISA-L-based codes
ISA-L v2.16 brings in support for AVX512-based erasure
coding, which has potential for 200% performance gain
over AVX2.  We already have v2.16 in the tree, but are
not using/building the AVX512 EC bits.  This patch adds
the missing files to the EC builds.
