kasan: only select SLUB_DEBUG with SYSFS=y
Building with KASAN and SLUB but without sysfs now results in a
build-time error:
WARNING: unmet direct dependencies detected for SLUB_DEBUG
Depends on [n]: SLUB [=y] && SYSFS [=n]
Selected by [y]:
- KASAN [=y] && HAVE_ARCH_KASAN [=y] && (SLUB [=y] || SLAB [=n] && !DEBUG_SLAB [=n]) && SLUB [=y]
mm/slub.c:4565:12: error: 'list_locations' defined but not used [-Werror=unused-function]

^~~~~~~~~~~~~~
mm/slub.c:4406:13: error: 'validate_slab_cache' defined but not used [-Werror=unused-function]
static long validate_slab_cache(struct kmem_cache *s)
This disallows that broken configuration in Kconfig.
