sci-misc/boinc: Bump to 7.20.2 ; plus OpenCL dependency fixes

BOINC can now detect and use the correct OpenCL implementations for
various situations. Therefore VIDEO_CARDS is questioned to pull in
the needed dependencies:

* video_cards_amdgpu   : dev-libs/rocm-opencl-runtime
  -> AMD GPUs supported by the amdgpu kernel driver. 64-bit only
* video_cards_intel    : dev-libs/intel-compute-runtime
  -> integrated Intel GPUs from Broadwell onwards. 64-bit only
* video_cards_nvidia   : media-gfx/nvidia-cg-toolkit
  -> USE="cuda" is enforced in this case
* video_cards_radeonsi : media-libs/mesa[opencl]

WARNING: Only nvidia+intel have been tested yet!
