* the oe udhcpc calls /usr/share/udhcpc/default.script which
calls run-parts -a "$1" /etc/udhcpc.d, so we can install
our script as 60ntp
* using /etc/default/udhcpc-ntp to have the possibility
to disable it on the target, its enabled per default

A lease bound/renewal could lead to the removal of a default
route set by pppd. Apply the same "dev $interface" filter that
would be used when using the "route" command.
Fixes: SYS#1163
CONFIG_IFUPDOWN_UDHCPC_CMD_OPTIONS was set to '-n' which means
"Exit with failure if lease cannot be immediately negotiated."
What we'd rather want is for udhcpc to continue to run until a lease can
finally obtain. Otherwise we have a race condition in case the DHCP
server is not reachable for a few seconds during system boot, and end up
having a system that is permanently without an IP address.
This fixes ORT#639
