Subject: [PATCH] selftests/futex: Fix -Wformat-security warnings in futex_priv_hash

Fix several -Wformat-security warnings in futex_priv_hash by passing
the test message strings as arguments to %s format specifiers in
ksft_*() logging functions.

This silences the warnings without changing the functional behavior
of the test.
