fix: report stored node-sysctls images globally

Browse Source 
The `--scheduler-k3s-global-node-sysctls-image` and `--scheduler-k3s-global-node-sysctls-pause-image` report flags returned the built-in default when nothing was stored, so an unset image could not be told apart from one set to the default. They now report the stored value like every other global flag, and new `--scheduler-k3s-computed-node-sysctls-image` and `--scheduler-k3s-computed-node-sysctls-pause-image` flags report the image that is actually used.
