RDC:Move rdc deamon to rocm path.

Installing files to standard path across each version and using
ldconfig has issues with side-by-side install.

Usage of RUNPATH/RPATH for ROCm to ensure all ROCm libraries are
picked without the need for ldconfig.

For RDC server to be picked up by systemctl, service config file
shall be a symlink from /lib/systemctl/system/rdc.service to
corresponding RDC file path in a given version of ROCm

For side-by-side install packages of RDC post install scripts
will be removed. Hence Use will have to set the symlink explicitly
for now.
