Several tests in the posix_timers selftest fail on kernels older than 6.13. These tests check for timer behavior related to SIG_IGN, which was refactored in the 6.13 kernel cycle, notably by commit caf77435dd8a ("signal: Handle ignored signals in do_sigaction(action != SIG_IGN)").

To ensure the selftests pass on older, stable kernels, gate the affected tests with a ksft_min_kernel_version(6, 13) check.
