[PATCH] tests/kms_cursor_legacy: reduce CI debug output

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

Use DRM_UT_CORE instead of DRM_UT_KMS in CI to reduce log volume while
retaining diagnostics. This applies to all subtests, including the
reported cursorA-vs-flipA-atomic-transitions case.

Log the actual debug mask instead of the hard-coded 0x4.
Intel CI output-limit validation is still pending.

Closes: https://gitlab.freedesktop.org/drm/i915/kernel/-/work_items/16961
