[PATCH pve-firewall v2 02/12] firewall: config: sort OPTIONS when serializing

[Arthur Bied-Charreton <a.bied-charreton@proxmox.com>]

Until now, firewall config serialization was iterating over the options
hash without sorting the keys, making the output non-deterministic.

Iterate over the sorted keys instead in format_options.
