When running containerd inside LXC, due to systemd being unable to execute
`modprobe overlay` inside the container (module is already loaded in host kernel).
This patch adds a `-` prefix to the `ExecStartPre` command, so that failures
are ignored, and the service can start as usual.

It is also useful when testing local changes, I just run:
sudo systemd-run -p Delegate=yes -p KillMode=process bin/containerd

This is needed for users on kernel older than 3.18 so they can avoid EBUSY
errors when trying to unlink, rename or remove a mountpoint that is present in
a shim namespace.
