self-tests code assumes 4k as the sectorsize and nodesize. This commit
enables the self-tests code to be executed on non-4k page sized
systems (e.g. ppc64).
To test all possible sectorsizes, this commit adds a sectorsize
array. This commit executes the tests for all possible sectorsizes and
nodesizes.
