tst: Add test for settimeofday
This code brings test to check if time on target machine is properly set. To avoid any issues with altering the time: - The time, which was set before the test was executed is restored. - The time is altered only when cross-test-ssh.sh is executed with --allow-time-setting flag Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
