shill: Increase receive buffer size for RTNL socket

We have seen some rare but nasty occurences of ENOBUFS errors on shill's
RTNL socket. While it is hard to say how exactly those errors come to
pass, we hope to be able to mitigate them by increasing the socket's
receive buffer size.

As an ancient kernel bug (http://marc.info/?m=134860874327843) currently
makes it default to a low hard limit on receive buffer size, we need to
leverage our root UID by using SO_RCVBUFFORCE.
