According to the systemd documentation, `infinity` can be used for all limits;
https://www.freedesktop.org/software/systemd/man/systemd.exec.html#Process%20Properties
> Resource limits may be specified in two formats: either as single value to set a
> specific soft and hard limit to the same value, or as colon-separated pair soft:hard
> (...) Use the string infinity to configure no limit on a specific resource.

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.
