bitbake: toaster: write pre-read conf file for build variables

We change the setting of variables from directly injection
into the set-up cooker to writing a conf file that is pre-read
on bitbake server startup. This is needed because the injection
can only happen after the variable set is parsed, and the variables
already inferred, so setting up variables happens too late.
