wic: add --fixed-size wks option
Added new option --fixed-size to wks. The option can be used to indicate
the exact size of a partition. The option cannot be added together with
--size, in which case an error will be raised. Other options that
influence automatic partition size (--extra-space, --overhead-factor),
if specifiec along with --fixed-size, will raise an error.
If it partition data is larger than the amount of space specified with
--fixed-size option wic will raise an error.
