bitbake: bitbake: move extra cache collection out of cooker

The collection of the extra caching data should not
be performed by the cooker, but supplied to it.
This patch will also streamline the code for launching servers
without a UI attached.

Based on a patch by Bogdan Marinescu <bogdan.a.marinescu@intel.com>
