cleaner: revise rules for emergency clean.

Normally we only clean when there is free space available for
dedicated cleaning segments.
However if space is tight we might need to clean to the main segment.
Do this only if there are no 'clean' segments (otherwise force a
checkpoint so those clean segments become free).

clean_reserved doesn't really factor into this decision.
