[BusyBox] Add mkdosfs tool (mkfs.msdos) [PATCH]

[Jason Schoon]

I can look into it.  To be honest, I didn't make many changes to the
mkdosfs code.  I simply ported it into busybox and made some size
reductions where necessary.

I ended up with an applet that added about 6KB or so to my busybox on
my PPC 8245 target.  I have 32 MB of RAM on my platform, and I only
need to format a 512 MB or less compact flash card, so it was
sufficient for my needs.
