Replace hrtimer based timer emulation with host timebase (ktime_t)

This avoids host load when guests are scheduled out, removes a

improvements easier.
I wonder if we're really winning with this. Guests should be
scheduled-out-but-not-halted rarely, and in all other cases we need to
keep the timer. A timer comparison on each guest entry might be
expensive (maybe not so much with tsc based timers).
