[roll] Roll fuchsia [lowpan][resolver] use ephemeral source port for upstream DNS queries
Update `on_start_dns_upstream_query` to bind the local UDP socket to
port 0 instead of 53.
Port 53 is reserved for listening DNS servers. Using port 0 allows
the OS to assign a random ephemeral port, properly supporting parallel
outbound queries.
A raw DNS query message with port 53 bound on local address:
```
2005:1234:abcd:100:b898:3f59:6689:62e9 2005:1234:abcd:100::e1 DNS 96 1 Standard query 0x67c9 AAAA threadgroup1.org
Internet Protocol Version 6, Src: 2005:1234:abcd:100:b898:3f59:6689:62e9, Dst: 2005:1234:abcd:100::e1
User Datagram Protocol, Src Port: 53, Dst Port: 53
Source Port: 53
Destination Port: 53
