BUG/MINOR: proxy: fix clang build error on "add backend" handler

This patch fixes the following compilation error :
  src/proxy.c:4954:12: error: format string is not a string literal
        (potentially insecure) [-Werror,-Wformat-security]
   4954 |         ha_notice(msg);
        |                   ^~~

No need to backport.
