[PATCH] simplify ext4 install boot option

[Eric Sandeen <sandeen redhat com>]

I think just "ext4" is enough at this point...

migration seems totally busted; the root fs and everything in its fstab
is mounted before the migration routine runs, so it doesn't get its
fs type changed until the *next* mount, which for this migration path
pretty well misses the window of opportunity.  :( 

So I figure maybe "ext4migrate" to enable it, but it's not really going
to do what you might hope...

Thanks,
-Eric
