8 is better than 10

It's quite common for the real pmtu to be 8 less than what was
advertised.

pay attention to EMSGSIZE errors when sending pmtu verification packets
...
and drop the pmtu accordingly
This way, when we actually *do* get pmtu info from the network/kernel
we can discover the correct pmtu much more quickly. Especially in the
absence of other traffic, forwarding of which was previously the only
place where we'd check for EMSGSIZE.

run weave in privileged container
...
...since on selinux (and possibly others) we encounter a "bind:
permission denied" error instead, most likely because weave is
attempting to bind a raw ip socket, which is a restricted operation on
those systems.
