Backport v2021← v2022dev3 iptables-nmap: Switch to http to avoid errors on QEMU

Backport from v2022dev3 to v2021 !329 (merged)

Test case of iptables-nmap fails on SDK with error

Unable to apt-get update in lxc container Certificate verification failed: The certificate is NOT trusted. The certificate issuer is unknown. Could not handshake: Error in the certificate verification. [IP: 199.232.142.132 443]

Since the problem is only present on QEMU without a clear cause, after checking that clock time is OK workaround it by using http instead of https.
