kmemtrace, kbuild: fix slab.h dependency problem in lib/decompress_bunzip2.c

Impact: cleanup

lib/decompress_bunzip2.c depends on slab.h without including it:

    CC      lib/decompress_bunzip2.o
  lib/decompress_bunzip2.c: In function ‘start_bunzip’:
  lib/decompress_bunzip2.c:636: error: implicit declaration of function ‘kmalloc’
  lib/decompress_bunzip2.c:636: warning: assignment makes pointer from integer without a cast
  lib/decompress_bunzip2.c: In function ‘bunzip2’:
  lib/decompress_bunzip2.c:682: warning: assignment makes pointer from integer without a cast
  lib/decompress_bunzip2.c:693: warning: assignment makes pointer from integer without a cast
  lib/decompress_bunzip2.c:726: error: implicit declaration of function ‘kfree’
  make[1]: *** [lib/decompress_bunzip2.o] Error 1
  make: *** [lib/] Error 2

It gets included implicitly currently - but this will not be the
case with upcoming kmemtrace changes.
