    fsck_msdosfs: avoid warnings about too-long initializer strings
    
    Mark `dot_name` and `dotdot_name` as as `__non_string`, to avoid
    warnings from clang 21 similar to:
    
        sbin/fsck_msdosfs/dir.c:466:39: error: initializer-string for character array is too long, array size is 11 but initializer has size 12 (including the null terminating character); did you mean to use the 'nonstring' attribute? [-Werror,-Wunterminated-string-initialization]
          466 | static const u_char dot_name[11]    = ".          ";
              |                                       ^~~~~~~~~~~~~
        sbin/fsck_msdosfs/dir.c:467:39: error: initializer-string for character array is too long, array size is 11 but initializer has size 12 (including the null terminating character); did you mean to use the 'nonstring' attribute? [-Werror,-Wunterminated-string-initialization]
          467 | static const u_char dotdot_name[11] = "..         ";
              |                                       ^~~~~~~~~~~~~
