Commit 8c1a381a ("mips: add asm/stat.h to UAPI compile-test
coverage") converted as follows:

  uid_t  -->  __kernel_uid_t
  gid_t  -->  __kernel_gid_t

The bit width of __kernel_{uid,gid}_t is 16 or 32-bits depending on
architectures.

MIPS uses 32-bits for them as in include/uapi/asm-generic/posix_types.h,
so the previous conversion is probably fine, but let's stick to the
arch-independent conversion just in case.

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]
