Subject: [PATCH] Kconfig: Move CONFIG_DEBUG_KMEMLEAK_TEST to samples/Kconfig

From: Chen Jun <c00424029@...wei.com>

commit 1abbef4f51724fb11f09adf0e75275f7cb422a8a
("mm,kmemleak-test.c: move kmemleak-test.c to samples dir")
make CONFIG_DEBUG_KMEMLEAK_TEST depend on CONFIG_SAMPLES implicitly.
And the dependency cannot be guaranteed by Kconfig.

move the definition of CONFIG_DEBUG_KMEMLEAK_TEST from lib/Kconfig.debug
to samples/Kconfig.
