selftests/futex: Fix format-security warnings in futex_priv_hash

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.

Thus prevent potential security issues and eliminate compiler warnings when
building with -Wformat-security.
