tools/latency-collector: Fix -Wformat-security compile warns

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);
