virtual/opencl: do not install README.gentoo

Having the list of available OpenCL runtimes stored in README.gentoo,
which was suggested during reviews of opencl-3 on gentoo-dev,
unfortunately violates the policy demanding virtuals not to install any
files. Revert to the original approach of using elog in pkg_postinst
directly.

-In order to take advantage of OpenCL you will need a runtime for your hardware.
-Currently included in Gentoo are:
-
- * open:
-    - dev-libs/intel-neo - integrated Intel GPUs from Broadwell onwards. 64-bit only;
-    - dev-libs/rocm-opencl-runtime - AMD GPUs supported by the amdgpu kernel driver.
-      Image support still requires a proprietary extension [1]. 64-bit only;
-    - media-libs/mesa[opencl] - some older AMD GPUs; see [2]. 32-bit support;
-
- * proprietary:
-    - dev-libs/amdgpu-pro-opencl - AMD Polaris GPUs. 32-bit support;
-    - dev-util/intel-ocl-sdk - Intel CPUs (*not* GPUs). 64-bit only;
-    - x11-drivers/nvidia-drivers[uvm] - Nvidia GPUs; specific package versions
-      required for older devices [3]. 32-bit support.
