[Shuah Khan]

Fix the following -Wformat-security compile warnings adding missing
format arguments:

latency-collector.c: In function ‘show_available’:
latency-collector.c:938:17: warning: format not a string literal and
no format arguments [-Wformat-security]
  938 |                 warnx(no_tracer_msg);
      |                 ^~~~~

latency-collector.c:943:17: warning: format not a string literal and
no format arguments [-Wformat-security]
  943 |                 warnx(no_latency_tr_msg);
      |                 ^~~~~

latency-collector.c: In function ‘find_default_tracer’:
latency-collector.c:986:25: warning: format not a string literal and
no format arguments [-Wformat-security]
  986 |                         errx(EXIT_FAILURE, no_tracer_msg);
      |
                         ^~~~
latency-collector.c: In function ‘scan_arguments’:
latency-collector.c:1881:33: warning: format not a string literal and
no format arguments [-Wformat-security]
 1881 |                                 errx(EXIT_FAILURE, no_tracer_msg);
      |                                 ^~~~
