Issue using vopono with non-steam games in steam because of sudo requirement

[ParetoOptimalDev]

Related to #189.

For instance:

Target: vopono
launch options: exec stremio

Results in:

/bin/sh\0-c\0/home/pod/.local/share/Steam/ubuntu12_32/reaper SteamLaunch AppId=2597603739 -- /home/pod/.local/share/Steam/ubuntu12_32/steam-launch-wrapper -- vopono exec stremio\0
chdir "./"

sudo: The "no new privileges" flag is set, which prevents sudo from running as root.
sudo: If sudo is running in a container, you may need to adjust the container configuration to disable the flag.

Does it work if you use the firejail approach here - https://github.com/jamesmcm/vopono/blob/master/USERGUIDE.md#creating-only-network-namespace ? - i.e. using vopono first separately to generate only the network namespace.

Also since it seems to be running in a container anyway, you might be able to specify the container to use the created network namespace directly, but I'm not familiar with the Steam launch wrapper details.
