Subject: [PATCH 5/5] clearfog: Move all extra bootargs to a special variable

I have two reasons for this, and both of them center around making it
possible to perform changes to the boot process.

It is quite dangerous to attempt to re-flash the entire card, including
the bootloader, on the fly. Moving as much bits as possible to the
environment makes it a bit easier to introduce important changes such
as, for example, volatile rootfs, later on.

The second one is for testing -- it's much easier to just rewrite one
reasonable variable. Changes no longer require struggling with overly
long lines (bootcmd), at least.
