libosinfo: new package

libosinfo contains "info about OSs, hypervisors and (virtual) hardware
devices".

It is a dependency of gnome-boxes (a virtual and remote machine
application).
gnome-boxes: new package

gnome-boxes is a simple GNOME 3 application to access remote or virtual
systems.

Tested by creating a Ubuntu 14.04 VM from ISO image and playing around
with it. I cannot seem to get keyboard input to the VM. Mouse works
though.
