wic: add --extra-partition-space option to set unused space
By default, the content of the partition is filled by the filesystem
without leaving any unused free space. The --extra-space flag adds
extra space to the filesystem size, not to the partition.
Unused free space after the filesystem can be useful for some cases,
such as encrypting a partition at runtime.
With --extra-partition-space 32M, we ensure that the last 32M of the
partition is unused: this space does not contain filesystem data and
can store the LUKS2 header.
The implementation sets a difference between the partition and
filesystem size:
- With --fixed-size, the extra part space is removed from the
filesystem size.
- Otherwise (with or without --size flag), the extra part space is
added to the partition size.
