Update base image version in Dockerfiles

Should hopefully fix issues that cropped up with arm builds failing due
to the sqlite libs from alpine 3.10 no longer being compatible with
alpine edge, which was probably never a safe assumption to begin with.

Correctly report and propagate kubeconfig write failures

Always validate K3S_URL if running agent.

Bump k3s-root to v0.6.0-rc3

As seen in issues such as #15 #155 #518 #570 there are situations where
k3s will fail to write the kubeconfig file, but reports that it wrote it
anyway as the success message is printed unconditionally. Also, secondary
actions like setting file mode and creating a symlink are also attempted
even if the file was not created.

This change skips attempting additional actions, and propagates the
failure back upwards.
