Retry veth device creation on failure

The veth device creation code run in two steps, first it looks
for two free veth device names, then it runs ip link to create
the veth pair. There is an obvious race between finding free
names and creating them, when guests are started in parallel.

Rewrite the code to loop and re-try creation if it fails, to
deal with the race condition.
