    bsnmpd: avoid warnings about too-long initializer strings
    
    Mark `UTC` as `__non_string`, to avoid a warning from clang 21 similar
    to:
    
        usr.sbin/bsnmpd/tools/libbsnmptools/bsnmptc.c:339:29: error: initializer-string for character array is too long, array size is 3 but initializer has size 4 (including the null terminating character); did you mean to use the 'nonstring' attribute? [-Werror,-Wunterminated-string-initialization]
        --- all_subdir_usr.sbin ---
          339 |         static const char UTC[3] = "UTC";
              |                                    ^~~~~

    (cherry picked from commit 3054e22e4524df24908d7e9379681c1ccf829b93)
