[PATCH] tests/kms_plane_cursor: reduce CI debug output

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

Use DRM_UT_CORE in CI to reduce KMS log volume while retaining CORE
diagnostics. This applies to all subtests, including overlay, which
reported truncated dmesg output.

Closes: https://gitlab.freedesktop.org/drm/i915/kernel/-/work_items/16960
