Adds falco 0.39.0 and falcoctl 0.10.0 rocks

Note that the Dockerfiles are identical to the previous versions. Thus, the
rockfiles are also the same.

Falco 0.39.0 comes with falcoctl 0.10.0, which is why we're building
that version as well.

Added the new versions into the sanity and integration tests.
