fix the following errors by using string format specifier and an empty
parameter:

seccomp_benchmark.c:197:24: warning: zero-length gnu_printf format
 string [-Wformat-zero-length]
  197 |         ksft_print_msg("");
      |                        ^~
seccomp_benchmark.c:202:24: warning: zero-length gnu_printf format
 string [-Wformat-zero-length]
  202 |         ksft_print_msg("");
      |                        ^~
seccomp_benchmark.c:204:24: warning: zero-length gnu_printf format
 string [-Wformat-zero-length]
  204 |         ksft_print_msg("");
      |                        ^~
