"inst busybox" no longer seems to work when busybox is at
/sbin/busybox. Reproduced on Fedora 18 (dracut-023-39.git20120910).
Use type -P to find the full path to busybox to solve this problem.
Currently in dracut busybox module, we hard-code the list of binaries
available in busybox. Actually we can get this list by running busybox
without any arguments.
Also, if find_binary() finds nothing, we would symlink $initdir/
which is not we expect.

On the OLPC XO-1, there is a noticable delay during boot while the
initramfs is loaded from disk and uncompressed, so we have an interest
in making it small. We are also pushed for disk space.
Using busybox instead of all the regular tools saves a lot of space.
I have not tried every module but the basics are working with busybox's
replacements. Our initramfs is now down to 1.9mb.
