Fixed DNS resolving A records when -ports is set

[kz0ltan]

DNS A records were not showing up in the JSON output if -ports was used or the port was added to the target domain name via -u or -l in <domain_name>: format.
The original code tried to use getDNSData with the URL.Host property which in the above cases included the port specification as well, so the DNS query failed, and no A records were added to the output.

This small change fixes that problem.

Before:

echo scanme.sh:443 | httpx -json | jq .a
# echo scanme.sh| httpx -ports 443 -json | jq .a

After:

echo scanme.sh:443 | ./httpx -ip -json | jq .a
