Profpatsch 799cdbd834 tailscale: add interfaceName option
tailscale allows to specify the interface name.
The upstream systemd unit does not expose it directly however, only
via the `FLAGS` environment variable.

I can’t be 100% sure that the escaping is correct, but this is as good
as we can do for now, unless upstream changes their unit file.
