lmp/bb-build: only use the sstate-cache mirror when it is necessary

Our build can be divided into two steps: 1 - build only using the sstate-cache 2 - build everything else missing On the step [1] we run bitbake for setscene only tasks and obvious this one is the only one that uses and reads the sstate-cache mirror. The step [2] will have 0% hit of cache available because everything has already been accelerated in the step [1]. In the step [2] everything will be build from scratch and the local sstate-cache will be populated with the new artifacts. This change will improve and significantly reduce the load generated on the sstate-mirror http server by our CI builds. Signed-off-by: Jose Quaresma <[email protected]>
