bitbake: bitbake & hob: modify some commands and call them from hob

This patch adds a new command to create an extra configuration
file, in order to create it from Hob.
Also, it calls the enable/disable data tracking when needed.
Modified the prefiles and postfiles variables because the cooker
expects some lists.
