Fix a problem that connection to syslogd fails. 

* fhandler_socket_local.cc (get_inet_addr_local): Change type from
  'static int' to 'int' to be callable from syslog.cc.
* syslog.cc (connect_syslogd): Use get_inet_addr_local() instead of
  getsockname() to retrieve name information of the syslogd socket.
