udp, polypath: Log `experiencing success receiving', etc.

We want to use the `experienced' mechanism to report success while
receiving.

But, previously, the udp_socks_afterpoll function which does the
reciving didn't have a suitable description (`socksdesc') available:
in particular, for polypath, it should print the interface name.

Solve this as follows:
 * Add a `desc' field to struct udpsocks, set by udp_socks_register
   (for polypath this duplicates interf->name, but we don't really
   care much about that as it's only one pointer).
 * Add a new argument to udp_socks_register to ensure we catch
   all the creation sites.
 * Have have udp_sock_experienced take a struct udpsocks*.

After all that, the new call to udp_sock_experienced is trivial.
