Replace size_t with __kernel_size_t to fix asm/shmbuf.h userspace
compilation errors like this:

/usr/include/asm-generic/shmbuf.h:28:2: error: unknown type name 'size_t'
  size_t   shm_segsz; /* size of segment (bytes) */

x32 is the only architecture where sizeof(size_t) is less than
sizeof(__kernel_size_t), but as the kernel treats shm_segsz field as
__kernel_size_t anyway, UAPI should follow.  Thanks to little-endiannes
of x32 and 64-bit alignment of the field following shm_segsz, this
change doesn't break ABI, and the difference doesn't manifest itself
easily.

Out of interest, is there a plan for merging these patches from Dmitry?
