fix: opt out of the SSH hardening inherited from napalm-linux

OpenMediaVault generates sshd_config from its own database; a drop-in
netOrk wrote would be dropped by the next apply of the SSH settings
without a word. harden_ssh_server = None makes netOrk's capability probe
answer no.

Requires napalm-linux 0.5.0; bumps to 0.1.1. NetOrk/netork#1027
