Subject: [PATCH] src/oping.c: always use "%s"-style format for
 printf()-style functions

`ncuses-6.3` added printf-style function attributes and now makes
it easier to catch cases when user input is used in palce of format
string when built with CFLAGS=-Werror=format-security:

    oping.c:1265:41: error: format not a string literal and no format arguments [-Werror=format-security]
     1265 |                                         hist_symbols_utf8[index]);
          |                                         ^~~~~~~~~~~~~~~~~

Let's wrap all the missing places with "%s" format.
