Minor consistency fixes.
They clear a couple of compiler format string warnings.
[1/2] is the fix of an obvious typo in the format specifier [2/2] is securing the print function against spurious format specifiers in passed paramater string

GCC 13.2.0 reported a format string warning:
step_after_suspend_test.c: In function ‘run_test’: step_after_suspend_test.c:92:32: warning: too many arguments for format [-Wformat-extra-args] 92 | ksft_print_msg("waitpid() failed: $s\n", strerror(errno)); | ^~~~~~~~~~~~~~~~~~~~~~~~
Fixing the typo $s into %s resolves the issue.

ksft_*() functions are unprotected against potential spurious format specifiers in msg.
Protecting the conversion with "%s\n" format string fixes the warning.
