EXPERIMENTAL: mogami: Repartition

WARNING: Do not use this if you don't know what you are doing

We're running out of space in kitkat on /system
and /cache (with dalvik-cache stored in there)

Let's repartition, giving:
 450mb in /system
 469,5mb in /data
 8mb in /cache

This requires a userspace change to store
dalvik-cache in /data instead of /cache
