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.
