[PATCH 2/5] dnsmasq: add handling of `cache-rr` to init script

[Paul Donald]

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

Tested on: 23.05.2
