Andrew Zaborowski 7ecdee6eaa autotests: p2p: Make waiting for dhclient more reliable
Make sure we wipe the leases file both for server and client, so that
dhclient doesn't try to re-use leases from previous tests (should really
happen) and waste time waiting for a reply.  Extend the timeout from 1s
to 5s, sometimes it takes dhclient 1s just to start.  Disable verbose
mode if not needed to avoid dhclient stalling if the pipe is not being
read.
