This reverts f9c87be6b42dd0f8b31a4bb8c6a44326879fdd1a, in a sense,
because that commit broke logging of "Connection from ..." when
git-daemon is run under xinetd.
This patch here computes the text representation of the peer and then
copies that to environment variables such that the code in execute()
and subfunctions can stay as-is.
