[PATCH 3/3] tests/kms_display_modes: Skip test if joiner display is connected

[Jeevan B]

High-resolution displays that support joiner modes can cause extended mode
tests to fail. This commit introduces a check to skip these tests if a
joiner mode display is connected, ensuring the test suite runs smoothly
without unnecessary failures.

v2: Add output name in skip message.
