Guard against negative time deltas

Despite the use of `erlang:monotonic_time/0`, it is still possible on
some platforms, such as sleeping/awakening laptops, for time to move
in surprising directions. When this happens, and a negative time delta
is passed to `timebin/1`, it crashes with:

bad arithmetic expression at math:log10/1 <= ioq_server:timebin/1(line:480)

This adds a guard to return `0` for negative numbers as well as zero.
