fsck_msdosfs: avoid warnings about too-long initializer strings

Browse Source 
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] = "..         ";
          |                                       ^~~~~~~~~~~~~
