This commit introduces the timerjitter test case, designed for assessing timer accuracy quickly. It is a simplified cyclictest implementation, optimized for fast and effective testing of timer precision. The program sets up a periodic timer and awaits the firing of SIGALRM. Upon signal arrived, it computes the time difference between consecutive periods. A smaller time difference indicates higher time accuracy. You can execute timerjitter without passing any arguments. Alternatively, you have the option to pass '-p' to print the time difference after each period, or provide additional arguments to customize the timer interval (in microseconds) and the number of test iterations.
