RSV wants /var/lib/osg/supported-vo-list for its vo-supported-probe. There are several situations in which we don't generate that file and the probe errors out. It turns out that since we report the supported VOs to the central collector via condor-ce, that probe is no longer useful. Dummy out the probe; we will remove it when we get removing probes worked out.
(This ticket was originally about modifying osg-configure to create supported-vo-list.)
