dnsmasq: fix handlers for options filter_rr and cache_rr

According to:
- https://github.com/openwrt/luci/blob/master/modules/luci-mod-network/htdocs/luci-static/resources/view/network/dhcp.js#L700
- https://github.com/openwrt/luci/blob/master/modules/luci-mod-network/htdocs/luci-static/resources/view/network/dhcp.js#L402

These two options should be of type `MultiValue` but here there're used as single value. This results in dnsmasq crashes when either of these options are set with multiple values, which leads to an invalid space-separated value.

As these options are designed to take multiple values, I think it's better to use list format eg. `list filter_rr 'AAAA'`, instead of `option filter_rr 'AAAA,HTTPS'`.

See: https://forum.openwrt.org/t/selecting-more-than-one-filter-arbitrary-rr-or-cache-arbitrary-rr-in-v24-10-0-crashes-dnsmasq/225801

Tested on 24.10.0
