[PATCH v2] selftests/proc: Fix string literal warning in proc-maps-race.c

[Sukrut Heroorkar <hsukrut3@xxxxxxxxx>]

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);
     |         ^~~~~~

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

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