[OE-core] [oe-core][PATCH 3/6] kernel.bbclass: use better number for KERNEL_PRIORITY

[Martin Jansa]

* there is no upgrade from 2.6.X to 3.X.Y
  last part of PV is used as kernel priority for u-a, but X is usually
  higher then Y in 3.x.x so use all 3 parts in one bigger number
* and make it weak assignment if this scheme doesn't work for some
  recipe
* if there are just 2 numbers in PV then last one is repeated twice
  (see linux-openmoko_3.2 example) but that should work fine too
