[PATCH] drm/client: Convert to VISIBLE_IF_KUNIT

[Maxime Ripard]

Commit 8fc0380f6ba7 ("drm/client: Add some tests for
drm_connector_pick_cmdline_mode()") was meant to introduce unit tests
for the static drm_connector_pick_cmdline_mode() function.

In such a case, the kunit documentation recommended to import the tests
source file directly from the source file with the static function to
test.

While it was working, it's generally frowned upon. Fortunately, commit
9c988fae6f6a ("kunit: add macro to allow conditionally exposing static
symbols to tests") introduced macros to easily deal with that case. We
can thus remove our include and use those macros instead.
