netlink: Use IFA_F_NODAD also while duplicating addresses from the host2024_04_26.d03c4e2
...not just for a single set address (legacy operation with
--no-copy-addrs). I forgot to add this to nl_addr_dup().
Note that we can have two version of flags: the 8-bit ifa_flags in
ifaddrmsg, and the newer 32-bit version as IFA_FLAGS attribute, which
is given priority if present. Make sure IFA_F_NODAD is set in both.
Without this, a Podman user reports, something on the lines of:
pasta --config-net -- ping -c1 -6 passt.top
would fail as the kernel would start Duplicate Address Detection
once we configure the address, which can't really work (and doesn't
make sense) in this case.
