Subject: dev-libs/beignet: do not try enabling OpenCL 2.0 support on
 unsupported ABIs

Beignet CMake scripts handle this the right way so let's work with them instead
of against them. Now if USE=ocl20 it will get enabled for abi_x86_64 and
gracefully fall back to 1.2 for the others, whereas USE=-ocl20 still explicitly
disables it for all ABIs.

With many thanks to aballier.

Gentoo-Bug: 622964

Package-Manager: Portage-2.3.6, Repoman-2.3.1
