Separate distribution packages for ICD loader and ICD

[inducer]

The rocm-opencl package should be split into two packages, the ICD loader (libOpenCL.so) and the ICD itself. Otherwise, it is likely that an already present system-wide ICD loader will be overriden. For those who are bitten by the same issue in the meantime, this will divert the file to not interfere with system-wide configuration:

dpkg-divert --divert  /opt/rocm/opencl/lib/x86_64/libOpenCL-amd.so.1 --rename  /opt/rocm/opencl/lib/x86_64/libOpenCL.so.1
