Matthew,
I able to reproduce this and I have the exact same error (mariadb log +
apparmor on host).

Your workaround is working but it seems that removing only these 3 lines
is sufficient:
> ProtectSystem=full
> PrivateDevices=true
> ProtectHome=true

You can leave this one:
> ExecStartPre=/usr/bin/install -m 755 -o mysql -g root -d /var/run/mysqld

Another workaround is to disable completely apparmor:

I think we should wait until some progress comes from
https://github.com/lxc/lxc/pull/2758.
