Port MTD structures to use 64-bit byte offsets instead of sectors.

Browse Source 
As per the discussion on issue 221745 we will be using 64-bit byte offsets
for the MTD partition table and converting to/from sectors internally in cgpt.
Existing interfaces do not change, eg sizes are still reported in sectors, only
the on-disk representation is affected.
