run_erl: Don't define _XOPEN_SOURCE on OS X
On MacOS X, defining _XOPEN_SOURCE usually *removes* features from header files. Therefore, we should not set _XOPEN_SOURCE to 600 since that will remove the prototype for vsyslog(). Setting it to an empty value or not including it will ensure that the vsyslog() prototype is included.
