Automate k0sctl version setting across test suites

Removes the need to make manual changes for k0sctl version bumps.
The version is obtained from hack/tool/go.mod which is updated
automatically by dependabot. All the other suites that use k0sctl
now get their k0sctl version by reading it from hack/tool/go.mod.
