[PATCH] selftest/futex: fix format-security warnings in futex_priv_hash

[Nai-Chen Cheng]

Fix format-security warnings by using proper format strings when
passing message variables to ksft_exit_fail_msg(),
ksft_test_result_pass(), and ksft_test_result_skip() function.

This prevents potential security issues and eliminates compiler warnings
when building with -Wformat-security.
