build: disable vbox on cygwin

Cygwin cannot build the vbox driver yet:

			       ^

Rather than trying to figure out how to get dynamic loading of
vbox to work under cygwin (since I don't even have a working vbox
setup to test whether it works), I'm going to be lazy and just
default to not even trying vbox on cygwin.
