[PATCH] wic/bootimg-efi: if fixed-size is set then use that for mkdosfs

[Randolph Sapp]

This is a bit of a compatibility issue more than anything. Some devices
get upset if the FAT file system contains less blocks than the
partition.

The fixed-size argument is currently respected by the partition creation
step but not by the file system creation step. Let's make it so the file
system respects this value as well.
