veth: delete device before creation to handle stale state

When a veth device already exists in the kernel (from a previous failed
cleanup or external creation), attempting to create it again with
NLM_F_EXCL fails with -EEXIST. This leaves the device in a broken state
where netifd marks it as present but cannot bring it up.
