The empty wic plugin is used to create unformatted empty partitions for wic
images.
To use it you must pass "empty" as argument for the "--source" parameter in
the wks file. For example:
part foo --source empty --ondisk sda --size="1024" --align 1024
Also adds a selftest for this plugin where the 'Fstype' column from 'wic
ls' should be empty for the second partition as listed in
test_empty_plugin.wks.
