Currently when using the num_parts parameter, partitions are aligned and
the end sector is one prior to the next start. This creates different
sized partitions. Create instead equally sized partitions by trimming the
end of each partition to the size of the smallest partition. This aligns
better with what one would expect from automatically created partitions and
can be helpful with testing things such as raid which often expect legs of
the same size. Minimal space is lost as the initial partition starting
size is calculated by dividing num_sectors by sdebug_num_parts.
