bitbake: cooker: Defer configuration init to after UI connection

Currently we end up parsing the base configuration multiple times as
initially, the right settings haven't come from the UI. We can defer
this until later in startup using runCommand as a trigger.

The advantage to doing this is improved startup times and ultimately
we should be able to avoid the double parse of the base configuration.
