[PATCH] mm,kmemleak-test.c: move kmemleak-test.c to samples dir

[Hui Su <sh_def@163.com>]

kmemleak-test.c is just a kmemleak test module, which
also can not be used as a built-in kernel module.
Thus, i think it may should not be in mm dir, and move
the kmemleak-test.c to samples/kmemleak/kmemleak-test.c.
Fix the spelling of built-in by the way.

 To check if you have all set up to use kmemleak, you can use the kmemleak-test
