    dnsmasq: add handling of `filter-rr` to init script
    
    dnsmasq v2.90 introduced `--filter-rr=<rrtype>[,<rrtype>...]`.
    
    uci config usage:
    
    config dnsmasq
        ...
        option filter_rr 'AAAA,CNAME,NXDOMAIN,SRV,...'
    
    The dnsmasq instance internally builds a linked list of RR to filter
    from the individually supplied parameters, so it's harmless to provide
    synonyms:
    
    ... --filter-A --filter-rr=A ...
    
    See https://forum.openwrt.org/t/resolving-query-type-65-to-local-address-for-ios-clients-in-dnsmasq/179504/23
