update/revolt: Fix mil count for che move after getting caught

When military catch che, their their count isn't updated for their
losses.  The count is later used when che consider moving to an
adjacent sector.  This could conceivably make them move instead of
stay.  Broken when Chainsaw 3 added land units.  Fix it.

Note that the sector's military count includes land units, but the
adjacent sectors' doesn't.  Should be improved some day; add a TODO
comment.
