Skip nx-ovlloader when disabling sysmodules startup flags

[clamintus]

This might be more convenient. From the Tesla Menu you can directly re-activate the other sysmodules (using overlays like for example ovl-sysmodules) without needing to connect to a PC. The only downside of this would be the possibility of nx-ovlloader causing the system to fail to boot on the latest update, but, I believe, it's a rather negligible risk. At least, it never happened to me.

Looking at the releases it doesnt look like firmwares break nx-ovlloader, or at least they haven't in a while. I myself use the Hekate toolbox/deepsea toolbox when nx-ovlloader is down but I understand it'd be more convenient if it was whitelisted

I'll decide on whether to merge it before the next aio release
