[PATCH] Re-order <linux/fs.h> includes to fix userland breakage

The following moves all includes <linux/fs.h> (except <linux/ioctl.h>
and <linux/config.h> down to below the existing __KERNEL__ test.  None
of these includes are needed by the user-visible portions of the header,
and in some cases can cause userland apps to break.

For example, LTP and sash with an empty <linux/autoconf.h> will fail
thusly:

  cc -Wall  -I../../include -g -Wall -I../../../../include -Wall    setrlimit02.c -L../../../../lib -lltp  -o setrlimit02
  In file included from /usr/include/asm/atomic.h:6,
                   from /usr/include/linux/fs.h:20,
                   from setrlimit02.c:46:
  /usr/include/asm/processor.h:68: error: `CONFIG_X86_L1_CACHE_SHIFT' undeclared here (not in a function)
  /usr/include/asm/processor.h:68: error: requested alignment is not a constant

Build/run tested with a glibc rebuild as well.
