[PATCH] cache/cooker: Pass databuilder into bb.cache.Cache()

[Richard Purdie <richard.purdie@linuxfoundation.org>]

Rather that the current mix of static and class methods, refactor
so that the cache has the databuilder object internally. This becomes
useful for the following patches for multi config support.

It effectively completes some of the object oriented work we've been
working towards in the bitbake core for a while.
