Possible improvement: align lock location with FreeBSD convention (/run/lock/podman-cni.lock -> /var/run/lock/podman-cni.lock)

[matias-pizarro]

Would it make sense to expose the location of the podman service lock file to a config item so it can be made to follow host OS convention (e.g. on FreeBSD /var/run/lock/podman-cni.lock instead of /run/lock/podman-cni.lock)?

From what I see this is currently handled in lines 28 and 100 of vendor/github.com/containers/common/libnetwork/cni/network.go

l.28 const defaultRootLockPath = "/run/lock/podman-cni.lock"

l.100 lockPath := defaultRootLockPath
