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

Impact: fix build

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

    CC      lib/decompress_inflate.o
  lib/decompress_inflate.c: In function ‘gunzip’:
  lib/decompress_inflate.c:45: error: implicit declaration of function ‘kmalloc’
  lib/decompress_inflate.c:45: warning: assignment makes pointer from integer without a cast
  lib/decompress_inflate.c:57: warning: assignment makes pointer from integer without a cast
  lib/decompress_inflate.c:65: warning: assignment makes pointer from integer without a cast
  lib/decompress_inflate.c:71: warning: assignment makes pointer from integer without a cast
  lib/decompress_inflate.c:154: error: implicit declaration of function ‘kfree’
  make[1]: *** [lib/decompress_inflate.o] Error 1
  make: *** [lib/] Error 2

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