Fix parsing of unknown arguments

From: Jan Safranek <address@hidden>

'ipmidetectd --foo' in current CVS HEAD (and all previous releases)
results in segmentation fault, because getopt_long argument is not properly
terminated.

Following patch adds the terminating entry, fixing ipmidetectd when parsing
unknown command line arguments.
