[igt-dev] [PATCH i-g-t v4 09/17] i915/perf: Explicitly state rendercopy needs for a test

[Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com>]

Let tests explicitly require rendercopy before running. This helps in
temporarily blocking these tests until rendercopy is available on new
platforms.
