Recent updates to the MSDOS tools (OE-core is now at 3.0.28) have made
it an error to overwrite an image using mkfs.vfat:
mkfs.vfat: file XXXX/tmp/work/nitrogen6x-poky-linux-gnueabi/network-demo-image/1.0-r0/boot.img already exists
mkfs.fat 3.0.28 (2015-05-16)
WARNING: exit code 1 from a shell command.
This patch fixes the problem by removing any old/stale images before
trying to create the VFAT file system images.
