Peter Bigot 8fbc83c651 tests: timer_api: avoid compounding errors in imprecise conversions 
When the timer frequency is not a multiple of 1000 converting between
ticks and milliseconds introduces error.  Avoid propagating the error
by converting divided values rather than dividing converted values.

Also compensate for observed rate differences between the busywait
clock and the timeout clock.
