Subject: [PATCH] This PR modifies conda-recipe to add post-link to dpctl

The post-link creates a symbolic link from $PREFIX/etc/OpenCL/vendors/intel-gpu.icd to /etc/OpenCL/vendors/intel.icd if one exists.

This is a work-around to ensure that OpenCL GPU device from system
installation can be found by OpenCL loader in intel-opencl-rt forthcoming
package.
