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 ...
