sparc: fix mis-use of __kernel_{uid,gid}_t in uapi/asm/stat.h

Commit 31a088b664d6 ("sparc: add asm/stat.h to UAPI compile-test
coverage") converted as follows:

  uid_t  -->  __kernel_uid_t
  gid_t  -->  __kernel_gid_t

It changed the field widths of struct stat because Sparc uses 16-bits for
___kernel_{uid,gid}_t as in arch/sparc/include/uapi/asm/posix_types.h.

The safe replacements across all architectures are:

  uid_t  -->  __kernel_uid32_t
  gid_t  -->  __kernel_gid32_t

as defined in include/linux/types.h.

A similar issue was reported for the android binder. [1]
