mkl-dnn: upgrade 1.2.2 -> 1.4

The name of project has changed to oneDNN. Enable GPU engine to be built
by default which would need clang layer to be included.

Also include two minor fixes to install logic that have been submitted
for review upstream.

+Subject: [PATCH 1/2] src/CMakeLists.txt: fix FindOpenCL.cmake source path
+
+The existing logic doesn't work when DESTDIR is being passed to cmake.
+The file is installed in DESTDIR/CMAKE_INSTALL_PREFIX/libdir while we're
+trying to copy it from CMAKE_INSTALL_PREFIX/libdir.
+
+Use the file from source tree instead.

+Subject: [PATCH 2/2] src/CMakeLists.txt: use value of DESTDIR
+
+Make sure that we're using the value of DESTDIR for the paths that are
+being created to look into paths of installed files. Ensure that
+cmake_install.cmake actually has $ENV{DESTDIR} which gets expanded if
+it's being passed to cmake.
