[igt-dev] [PATCH i-g-t] tests/i915: Skip gem_exec_fair on GuC based platforms

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

The gem_exec_fair test is specifically testing scheduler algorithm
performance. However, GuC does not implement the same algorithm as
execlist mode and this test is not applicable. So, until sw arch
approves a new algorithm and it is implemented in GuC, stop running
the test.
