Subject: [PATCH] powerpc/32s: Include <linux/moduleloader.h> header file to fix a warning

In commit 2edb16efc899 ("powerpc/32: Add KASAN support") support for
KASAN has been added. However building it as module leads to (warning
treated as error with W=1):

  arch/powerpc/mm/kasan/kasan_init_32.c:135:7: error: no previous prototype for 'module_alloc' [-Werror=missing-prototypes]

Make sure to include <linux/moduleloader.h> to provide the following
prototype: module_alloc.
