Subject: selftests/proc: fix string literal warning in proc-maps-race.c
Date: Tue, 5 Aug 2025 00:56:14 +0200

This change resolves non literal string format warning invoked for
proc-maps-race.c while compiling.

proc-maps-race.c:205:17: warning: format not a string literal and no format arguments [-Wformat-security]
 205 |                 printf(text);
     |                 ^~~~~~
proc-maps-race.c:209:17: warning: format not a string literal and no format arguments [-Wformat-security]
 209 |                 printf(text);
     |                 ^~~~~~
proc-maps-race.c: In function `print_last_lines':
proc-maps-race.c:224:9: warning: format not a string literal and no format arguments [-Wformat-security]
 224 |         printf(start);
     |         ^~~~~~

Add string format specifier %s for the printf calls in both
print_first_lines() and print_last_lines() thus resolving the warnings.

The test executes fine after this change thus causing no effect to the
functional behavior of the test.
