compaction_manager: run_offstrategy_compaction: retrieve owned_ranges…

… from compaction_state

perform_offstrategy is called from try_perform_cleanup
when there are sstables in the maintenance set that require
cleanup.

The input sstables are inserted into the compaction_state
`sstables_requiring_cleanup` and `try_perform_cleanup`
expects offstrategy compaction to clean them up along
with reshape compaction.

Otherwise, the maintenance sstables that require cleanup
are not cleaned up by cleanup compaction, since
the reshape output sstable(s) are not analyzed again
after reshape compaction, where that would insert
the output sstable(s) into `sstables_requiring_cleanup`
and trigger their cleanup in the subsequent cleanup compaction.

The latter method is viable too, but it is less effficient
since we can do reshape+cleanup in one pass, vs.
reshape first and cleanup later.
