Subject: [PATCH] binfmt_misc: include what is used

The include list still reflects code that left this file years ago:
nothing here uses sched/mm.h, pagemap.h, namei.h, syscalls.h or
anything from fs/internal.h anymore, mount.h and the bm_fs_type
forward declaration lost their last user when the pinned bm_mnt
machinery was removed. Drop all of that and instead spell out the
headers the file actually relies on but so far pulled in
transitively: bitops, bits, bug, cleanup, cred, kstrtox, printk,
refcount, string and user_namespace. With that nothing needs the
kernel.h grab bag anymore, so it goes too, and the list is sorted
alphabetically.
