mkjffs2: add lzo support
This adds support for building lzo images for root (and updates the
kernel accordingly, as LZO support wasn't compiled into the jffs2
driver). However, I'm not sold on LZO, so I haven't enabled it by
default. According to my tests, zlib left 540MB free, and bootup took
97s, while lzo left 505MB free, and bootup took 91s. Program startup
time appeared to be about the same. I'm not convinced that the 6s
bootup time improvement is worth it.

mkjffs2: add (redboot) partition support
We now create a 50MB boot partition, and the rest goes to a root
partition. This shaves 7s off of bootup, as OFW only has to mount
/boot. It also provides us the opportunity to use other filesystems
in /, as long as we keep /boot using jffs2.

olpc.fth: auto-detect boot device during boot
Rather than hardcoding nand:\ or disk:\ (which is incorrect in the case
of sd:\), read the /chosen/bootpath device tree property to determine
which device is being booting from, and use that variable. This fixes
SD booting (which works now; tested!)

initchroot: update kernel and custom initramfs-tools
This kernel has the majority of things built as a module, and uses an
initrd. Some initramfs customizations are necessary, so provide
a custom initramfs-tools for now.

olpc.fth: add video=lxfb as a kernel argument
This is only necessary if lxfb is compiled as a module, but it doesn't
hurt. It tells the debian initramfs to load lxfb (so it gets loaded
as quickly as possible).

initchroot: add a workaround for #314334
jffs2 doesn't support shared mmap, so apt explodes (#314334). This
was the reason why we were mounting /var/cache/apt/cache over tmpfs;
readd the mount, and update apt.conf accordingly.
