When proxmox-file-restore invokes QEMU, the PID file is a (temporary)
file that's already unlinked, so resolving the absolute path here
failed.
It should not be a critical error when the PID file unlink handler
can't be registered, because the path can't be resolved for whatever
reason. Just turn it into a warning instead.
