Confinement doesn't work on arch (manjaro) linux

[Alan Pope 🍺🐧🐱 🦄]

$ snap version
snap 2.30
snapd 2.30
series 16
manjaro
kernel 4.9.88-1-MANJARO

$ hello-world.evil
Hello Evil World!
This example demonstrates the app confinement
You should see a permission denied error next
If you see this line the confinement is not working correctly, please file a bug

Maybe we could alter the message to indicate that this applies to systemd where snaps are actually confined. OTOH, i see that this is only visible if you issue `snap debug confinement` command. Including this information in say, `snap version` would make it more accessible.

Proposed a small patch to include confinement mode in `snap version` output. If this is merged we will be able to update hello-world.evil to suggest looking at current confinement mode before filing a bug to snapd.
