    sys/font.h: avoid warnings about too-long initializer strings
    
    Mark `font_header::fh_magic` as `__non_string`, to avoid a warning from
    clang 21 similar to:
    
        /usr/src/usr.bin/vtfontcvt/vtfontcvt.c:763:15: error: initializer-string for character array is too long, array size is 8 but initializer has size 9 (including the null terminating character); did you mean to use the 'nonstring' attribute? [-Werror,-Wunterminated-string-initialization]
          763 |                 .fh_magic = FONT_HEADER_MAGIC,
              |                             ^~~~~~~~~~~~~~~~~
        /usr/obj/usr/src/amd64.amd64/tmp/usr/include/sys/font.h:109:27: note: expanded from macro 'FONT_HEADER_MAGIC'
          109 | #define FONT_HEADER_MAGIC       "VFNT0002"
              |                                 ^~~~~~~~~~
