[PATCH i-g-t 2/2] tests/kms_cursor_legacy: Use preferred modifier for non-cursor framebuffers

[Jeevan B <jeevan.b@intel.com>]

Stop hardcoding DRM_FORMAT_MOD_LINEAR for primary test framebuffers.
Instead, use IGT_FORMAT_MOD_PREFERRED. This allows IGT to select a
tiling mode supported by the platform via capability checks, avoiding
per-platform modifier policies in tests as tiling support evolves.
