use arm64 compatible docker image for startup script

[JacobSteelsmith]

This should fix #21 . I've created a helm package manually from the repository and installed it to an AWS cluster. The pod shows running in kubectl and the logs show the script ran. The tag for the image is the most recent that supports arm64. I have not tested this on a amd64 setup.

Hey @JacobSteelsmith, sorry for the delays in reviewing this. after doing load testing, it doesn't appear we would need to modify these kernel settings. I'm testing a PR right now. If it performs similarly, we'll remove this startup script from the chart.

It runs on my arm64 k3s cluster (4x pi4s) after making the suggested changes

Thanks for your contributions @sawariz0r. We've actually ended up stop using the daemonset, as the sysctl tuning isn't necessary with the latest livekit.
