examples: add improved networkd-dispatcher script
Add a separate example script for networkd-dispatcher. Check the
OperationalState and AdministrativeState variables to wait for the
routable+configured state, where IP addresses of NTP servers should
actually be routable. The script needs to be additionally installed
in the configured.d directory.
Remove networkd-dispatcher support from the NetworkManager dispatcher
script.

socket: ignore zero if_index in timestamping pktinfo
The kernel fills the if_index of SCM_TIMESTAMPING_PKTINFO from the
napi id of the packet (put_ts_pktinfo() in net/socket.c). Some drivers
keep their napi instances on an internal dummy device (e.g. ti cpsw).
Kernels without CONFIG_NET_RX_BUSY_POLL cannot resolve any napi id.
In both cases the lookup fails and the if_index is 0.
get_interface() then failed. Valid HW timestamps were dropped. The
less accurate kernel timestamps were used instead.
Zero is not a valid interface index. Ignore it when extracting the
control messages, so the timestamping if_index keeps its
INVALID_IF_INDEX initialization and the existing fallback to the
if_index of the message itself applies.
