Raphael S. Carvalho 322f194032 sstables: Fix leveled compaction strategy ...

There is a problem in the implementation of leveled compaction strategy that
prevents level 1 from being compacted into level 2, and so forth. As a result,
all sstables will only belong to either level 0 or 1. One of the consequences
is level 1 being overwhelmed by a huge amount of sstables.

The root of the problem is a conditional statement in the code that prevents a
single sstable, with level > 0, from being compacted into a subsequent level
that is empty or has no overlapping sstables.

Fixes #1180.
