[PATCH v1 2/2] selftest: breakpoints: clear the format string warning and secure the output

[Mirsad Todorovac <mirsad.todorovac@xxxxxxxxxxxx>]

GCC 13.2.0 compiler reported the following warning:

breakpoint_test.c: In function ‘check_success’:
breakpoint_test.c:287:17: warning: format not a string literal and no format arguments [-Wformat-security]
  287 |                 ksft_test_result_pass(msg);
      |                 ^~~~~~~~~~~~~~~~~~~~~
breakpoint_test.c:289:17: warning: format not a string literal and no format arguments [-Wformat-security]
  289 |                 ksft_test_result_fail(msg);
      |                 ^~~~~~~~~~~~~~~~~~~~~

ksft_*() functions are unprotected against potential spurious format specifiers
in msg.

Protecting the conversion with "%s\n" format string fixes the warning.
