ipc: avoid context line in generated exception

The filename and line number of the "aborted" message is
needless noise and confusing when dealing with errors
which already triggered ipc_fail.  So add a newline to
ensure Perl doesn't add context information if it needs
to `die' or `warn' on that message.
