Use ccache for builder builds

[Molter73]

Description

This is currently under test, from local testing the initial build becomes incredibly slow, which might mean this is not viable for cross compiled images (ppc64le, s390x). However, subsequent builds are MUCH faster, so if we can power through the first run, we might be able to speed up the builder build process. If this is successful we might want to look into doing something similar for the collector binary build.
