Subject: [PATCH] fuse: use kernel headers when __KERNEL__ is set

Commit 7e98d53086d18c877cb44e9065219335184024de (Synchronize fuse
header with one used in library) added #ifdef __linux__ around
defines if it is not set.  The kernel build is self-contained and
can be built on non-Linux toolchains.  After the mentioned commit
builds on non-Linux toolchains will try to include stdint.h and
fail due to -nostdinc, and then fail with a bunch of undefined
type errors.

Change the #ifdef to check for __linux__ or __KERNEL__ so that
it uses the kernel typedefs if __KERNEL__ is set.

I think this should go in v3.9, without it bare-metal toolchains
that don't define __linux__ will fail to compile the kernel, and
cross-compiles from non-linux hosts will probably also fail.
