nixos/prometheus-exporters/wireguard: add support for -s switch

Browse Source 
Since version 3.0 all allowed IPs and subnets are exposed by the
exporter. With `-s` set on the CLI, instead of a comma-separated list,
each allowed IP and subnet will be in a single field with the schema
`allowed_ip_<index>`.

By default, all allowed IPs and subnets are comma-separated in the

a single IP and subnet will be listed in fields like <literal>allowed_ip_0</literal>,
<literal>allowed_ip_1</literal> and so on.
