Comment 52 for bug 799997

Did some experiments and dropping the space from the bad chars makes it work for me as well.
Added a change for that and also enqueued the addition of quotes to the static rules.

I still expect issues with spaces down the road in some parts of libvirt, but if spaces are going to be forbidden it is not virt-aa-helper to do so - instead it would be a per HVM type check and/or the xml schema.
I will submit all that upstream together with some other virt-aa-helper changes I work on in a few days.
