Kernel: Remove SYS_SLEEP and cleanup SYS_NANOSLEEP

Browse Source 
`sleep` is now implemented in terms of `nanosleep`. `nanosleep` is now
more precise and handles overflow when calculating wakeup time. I don't
think anything was depending on this, but I could see a program sleeping
for max time to block until signal.
