SWDEV-301289 - Point to local AMD OpenCL via OCL_ICD_FILENAMES

The OCL_ICD_FILENAMES env var contains a list of OpenCL platforms that
the ICD should prepend to the list of reported platforms. Since the
built amdocl library will show up as the first platform, we can tell
ocltst to always run with platform 0. This way we guarantee that the
correct binary is being loaded.

Using this env var also makes programming LD_LIBRARY_PATH redundant
for Linux.
