graphics/{index}_valid_opengl_renderer_{product_slug}: the "DRI_PRIME=1" behavoir is not excepted as test case

[Leon Liao]

This test case is not property on a desktop machine when the monitor is connected to an AMD graphic card directly.

The "DRI_PRIME=1" is a toggle between amd and intel renderer.

The original renderer is AMD.
$ glxinfo | grep 'OpenGL renderer string'
OpenGL renderer string: AMD POLARIS12 (DRM 3.40.0, 5.10.0-1003-oem, LLVM 10.0.0)

When applied the DRI_PRIME=1, the renderer is intel.
$ DRI_PRIME=1 glxinfo | grep 'OpenGL renderer string'
OpenGL renderer string: Mesa Intel(R) Graphics (RKL GT1)
