Kernel: Make CLOCK_MONOTONIC respect the system tick frequency
The time returned by sys$clock_gettime() was not aligned with the delay
calculations in sys$clock_nanosleep(). This patch fixes that by taking
the system's ticks_per_second value into account in both functions.
This patch also removes the need for Thread::sleep_until() and uses
Thread::sleep() for both absolute and relative sleeps.
This was causing the nesalizer emulator port to sleep for a negative
amount of time at the end of each frame, making it run way too fast.
