dhcp: T9278: do not append the VRF option twice to ip route commands

01-vyos-cleanup builds its route deletion with an explicit "vrf <name>". The ip()
wrapper caught that command and delroute() appended $VRF_OPTION again, so both
"ip route show" and "ip route del" ran with "vrf red vrf red". The FRR-down
kernel fallback had the same flaw.

Add vrf_option(), yielding $VRF_OPTION only when the arguments carry no "vrf"
token, and use it in both places. The append cannot simply be dropped, as
delroute() is also reached without a VRF. iptovtysh() parses single fields and
was never affected.
