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";
| ^~~~~
