qxl max_outputs: ostype can be undefined, assume linux

Out code behaves like either l26 or other when the ostype is
undefined, both are not common as our webinterface _always_ sets the
ostype.

If one configured QXL with a VM as output device but does not has an
ostype set, and that works without "max_outputs=4" it really should
work with none too.
