qemu: Allow spaces in disk serial

https://bugzilla.redhat.com/show_bug.cgi?id=1195660

There's been a bug report appearing on the qemu-devel list, that
libvirt is unable to pass spaces in disk serial number [1]. Not only
our RNG schema forbids that, the code is not prepared either. However,
with a bit of escaping (if needed) we can allow spaces there.
