wic: use kB for the partitions size

Use kB instead of MB for the partition size to get a better granularity.

This is needed on some SoC (i.mx, omap) where it is necessary to create
partitions as small as 64kB.

Keep the backward compatibility by assuming MB when no unit is provided.

        The following are supported 'part' options:
 
-         --size: The minimum partition size in MBytes. Specify an
-                 integer value such as 500. Do not append the number
-                 with "MB". You do not need this option if you use
-                 --source.
+         --size: The minimum partition size. Specify an integer value
+                 such as 500. Multipliers k, M ang G can be used. If
+                 not specified, the size is in MB.

          --source: This option is a wic-specific option that names the
                    source of the data that will populate the
