Verity: dump device sizes.

Browse Source 
Calculating device sizes for verity devices is a little bit tricky,
Data, hash and FEC can share devices or it can be a separate devices.

This patch prints used device sizes in veritysetup dump command,
but it requires that user specifies all values that are not stored
in superblock (like a FEC device and FEC roots).
