Refactor SeaGRUB floppy creation code
Related issue #553
Previously, the GRUB boot image and core image were concatenated
together and padding added to create a (pseudo) floppy image.
However, testing revealed that GRUB has issues dynamically loading
modules from $prefix if $prefix is not located on the same device
from which GRUB booted.
In order to get around this issue, a proper 2.88MiB floppy image is
created using mkfs.fat with GRUB modules copied to directories on
the filesystem (i.e, /boot/grub/i386-pc). The 2.88MiB filesystem
size is necessary to be able to fit all modules onto the image.
New functions added to grub-helper:
* grub_floppy_image_mmd (create directories on image using mtools mmd)
* grub_floppy_image_mcopy (copy files to image using mtools mcopy)
