Subject: [PATCH] sstables: stop including unused expensive headers

database.hh is expensive to include, and turns out it's no longer
needed. also stop including other unused ones.

build time of sstables.o reduces by ~3% (cleared all caches and set
cpu frequency to a fixed value before building sstables.o from
scratch)
