fix mount usb

On Fedora 7 usbfs is mounted in /etc/rc.d/rc.sysinit as

mount -n -t usbfs /proc/bus/usb /proc/bus/usb

vboxusers can thus not use usb; all usb devices will be shown greyed out. The following command gives vboxusers access access to use usb in clients.

mount -t usbfs -o remount,devgid=$(awk -F: '/^vboxusers:/{print $3}' /etc/group),devmode=664  /proc/bus/usb /proc/bus/usb
