drirc: Add glsl_zero_init workaround for GpuTest
GiMark benchmark from GpuTest has such code in VS:
out vec4 lightDir0;
out vec4 lightDir1;
...
lightDir0.xyz = lp0 - vVertex.xyz;
lightDir1.xyz = lp1 - vVertex.xyz;
In FS:
float distSqr = dot(lightDir0, lightDir0);
So due to the usage of uninitialized .w channel in the dot product,
distSqr may become undefined which results in many black dots
in the test on Iris.
In https://www.geeks3d.com/forums/index.php/topic,6242.0.html
developer stated that this benchmark most likely won't be updated.
Closes: https://gitlab.freedesktop.org/mesa/mesa/issues/1919
