Subject: [PATCH] network-legacy/ifup: dhclient should be started in oneshot
 mode

since we handle the retries explicitly via rd.net.dhcp.retry

Without -1 if user sets ip=dhcp6 and there is no dhcp on the network,
dhclient seems to wait indefinitely, ignoring rd.net.timeout.dhcp

(cherry picked from commit 2181c80c91f05bfae5e50de2f502e363b0219bae)

Resolves: #1787620
