Adapt packages for rootless VPN

[jdknives]

Feature description

As pointed out by @ersonp here, we need to set correct permissions and ownership for the VPN-client binary. This likely needs to be changed in the package scripts for Debian and MacOS.

The above fix does not actually address the underlying issue and is simply using root client. We need to check whether the pacakges work with the current rootless setup and if they have the same issue documented in above ticket, revert to using root.
