selftests: timers: Fix abs() warning in posix_timers test
commit ed366de8ec89d4f960d66c85fc37d9de22f7bf6d upstream. Building with clang results in the following warning: posix_timers.c:69:6: warning: absolute value function 'abs' given an argument of type 'long long' but has parameter of type 'int' which may cause truncation of value [-Wabsolute-value] if (abs(diff - DELAY * USECS_PER_SEC) > USECS_PER_SEC / 2) { ^ So switch to using llabs() instead.
