Partially revert "Clarify who learns about ContactInfo."

This reverts the torrc.sample.in changes from commit
66a04a6ac334775dc396025e0c15fa49eca138a7.

We're going to not make this change in 0.2.4, since changing
torrc.sample.in makes all the debian users do some pointless
busywork. see tor-dev discusion of 9 Oct 2013.
