VPM-B ceiling: calculate deco_time similar to planned VPM-B dives

Browse source 
When planning a VPM-B dive, the "deco time" ends at surfacing, which is after
ascending after a full-minute deco stop is complete, after ceiling clears. We
should take this into account when calculating the ceiling outside of the
planner.
