nixos/stc: Improve mount unit handling
We should sometimes restart the units rather than reloading them so the changes are actually applied. / and /nix are explicitly excluded because there was some very old issue where these were unmounted. I don't think this will affect many people since most people use fstab mounts instead but I plan to adapt this behavior for fstab mounts as well in the future (once I wrote a test for the fstab thingies).
