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