Instead of running `go list` every time (very slow),
cache the results in the build folder and include it.

Add a shell helper script, to make the Makefile more
readable. Use regular "makedepend" syntax for output.

Make sure that all invocations are identical, before trying to make
a function out of it. Also clean up whitespace and similar changes.

Having a phony target as a minikube dependency means that
it always needs to be rebuilt/copied, which is unnecessary.

Also clean up and simplify the syntax, thereby avoiding the
current copy/paste errors (that always come with duplication)

I'm not sure of a better way to ensure /tmp exists in a from scratch container,
but glog appears to just explode without it.

Use the localkube binary built from CI in the integration tests.

This makes the minikube build simpler and the the binary smaller.
Localkube will always be remotely fetched and locally cached on the
host.
