Staging: fbtbt: Replace timespec with ktime_t
struct timespec will overflow in year 2038, so replace it with ktime_t. And replace functions that use struct timespec, timespec_sub with ktime_sub. Also use monotonic time instead of real time, by replacing getnstimeofday with ktime_get, to be more robust against leap seconds and settimeofday() calls.
