Subject: [PATCH 6/8] kemleak-test: build as module only

From: Daniel Baluta <dbaluta@...acom.com>

mm/kmemleak-test.c is used to provide an example of how kmemleak
tool works.

Memory is leaked at module unload-time, so building the test
in kernel (Y) makes the leaks impossible and the test useless.

Qualify DEBUG_KMEMLEAK_TEST config symbol with "depends on m",
to restrict module-only building.
