Fix bug#6781: Use 127.0.0.1 for local hosts, not "localhost".

* lisp/server.el (server-start): Revert part of 2010-08-08 change.  Using
  address 127.0.0.1 for local host is now done in Fmake_network_process.
* src/process.c (Fmake_network_process): When arg :host is 'local,
  use address 127.0.0.1, not name "localhost".
