dist_utils: Eliminate crash when list_to_existing_atom/1 fails

In the following scenario list_to_existing_atom/1 may crash
during handshake:

  Start a node in one window:

     erl -sname adam@localhost

  Start another node in another window:

     erl -sname bertil

  In this node, ping the first node (use the actual hostname
  in the command):

    net:ping(adam@hostname).

There will be an error report similar to:

=ERROR REPORT==== 27-May-2010::15:03:14 ===
Error in process <0.40.0> on node 'bertil@hostname' with exit value: {badarg,[{erlang,list_to_existing_atom,
["adam@localhost"]},{dist_util,recv_challenge,1},{dist_util,handshake_we_started,1}]}

Eliminate the crash and the error report by catching the call to
list_to_existing_atom/1 and do a clean shutdown if it fails.
