rate: fix rounding error in tokensFromDuration

tokensFromDuration performs a unit conversion by multiplying the limit
by the duration in seconds.

Make tokensFromDuration perform conversion by unit-wise multiplication
of limit by seconds and nanoseconds, instead of the conversion to
time.(Duration).Seconds that truncated the nanoseconds.

Fixes golang/go#34861
