runtime vulkan-tools hwdata clinfo(?) beignet

The beignet package has been removed from Debian and Ubuntu because it fails to build with current versions of LLVM/Clang (https://bugs.debian.org/974792). Hence, I am closing its bugs.

It is replaced by pocl-opencl-icd (on Ivy Bridge/Haswell = ix-3xxx/4xxx) and intel-opencl-icd (on Broadwell and later).
