[PATCH v2025.09.y 20/58] kbuild: fold rmdirs into rmfiles

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

From: Ahmad Fatoum <a.fatoum@barebox.org>

Linux doesn't differentiate between the two either and by adopting that,
we can have intermediary .tmp_*/ directories automatically deleted when
cleaning.

(cherry picked from commit 9914f8fdddac8ecf7fd8f3e8ab071a5fb86fb160)
