packages: move floppy utilities into a new package

[ivy]

Summary

no one uses floppy disks anymore. move fd utilities into a new package.

[ziaee]

Floppies might be a tough thing to waste the fd namespace on. What if we called it something that was still short but less ambiguous like floppies, similar to how we have manuals?

[ivy]

i appreciate the concern but i don't know what else we'd use "fd" for - it's not like we need a package of file descriptors (in case people run out). since all the tools start are called fd* and floppy disks were historically /dev/fd* this seems like a good name.

[imp]

Imho, "fd" is a fine name... we'll likely retire the driver soon after we retire the i386 kernel. Keeping for 15, so the split makes sense.
