sparc: add asm/stat.h to UAPI compile-test coverage

asm/stat.h is currently excluded from the UAPI compile-test for
ARCH=sparc because of the errors like follows:

  In file included from <command-line>:
  ./usr/include/asm/stat.h:11:2: error: unknown type name 'ino_t'
     11 |  ino_t   st_ino;
        |  ^~~~~
    HDRTEST usr/include/asm/param.h
  ./usr/include/asm/stat.h:12:2: error: unknown type name 'mode_t'
     12 |  mode_t  st_mode;
        |  ^~~~~~
  ./usr/include/asm/stat.h:14:2: error: unknown type name 'uid_t'
     14 |  uid_t   st_uid;
        |  ^~~~~
  ./usr/include/asm/stat.h:15:2: error: unknown type name 'gid_t'
     15 |  gid_t   st_gid;
        |  ^~~~~

The errors can be fixed by prefixing the types with __kernel_.

Then, remove the no-header-test entry from user/include/Makefile.
