Fix GCC warning:

    src/dbus.c: In function ‘near_dbus_encode_string’:
    src/dbus.c:71:37: error: format ‘%x’ expects argument of type ‘unsigned int’, but argument 3 has type ‘int’ [-Werror=format=]
       71 |    g_string_append_printf(str, "_%02x", tmp);
          |                                  ~~~^   ~~~
          |                                     |   |
          |                                     |   int
          |                                     unsigned int
          |                                  %02x
