libfdisk: fix issues with very small partitions
- cfdisk: minimal partitions size is 1 sector
- dos: when align last sector then don't set partition size to zero
for very small partitions.
- don't ignore tiny partitions before free space when define
free-space start offset
- improve some debug messages
