[Piglit] [PATCH 2/2] framework: double the number of concurrent tests per core

[Marek Olšák]

From: Marek Olšák <marek.olsak at amd.com>

This makes piglit 16% faster, because 1 thread per core uses only 85%
of the CPU. I don't know why the CPU is idle at times, but I guess it's
due to waiting for fences.
