gf-productiontests: add drm version of tests
Add drm version of guf_pixeltest and guf_touchtest to gf-productiontests package/recipe.
These DRM tests are needed for iMX devices with drm/kms support.
A following MR needs to be merged first: seco-ne/tools/gf-productiontests!103 (merged)
Passed build pipeline with both changes: https://git.seco.com/seco-ne/yocto/manifest/-/pipelines/90903
