dtrace: remove functionality of dtrace_os_exit() as deprecated

This function is in its current form no longer called from anywhere, but since
it is exported someone could (maliciously) still call it and cause a mess.  We
therefore issue a warning and do not do anything else.  This will be removed in
a future version.
