When wait channel names are displayed in FreeBSD e.g. by top(1), only
6 characters of the string are shown. This causes VirtualBox processes
to display "IPRT S" which isn't particularly distinctive.
The patch below changes the string to VBoxIS which I hope is distinct and
reasonably meaningful. I'm not yet familiar enough with VirtualBox's
internals to propose a better name, so if there's a better 6-character
description go ahead and use that.
