[Libosinfo] [v2] Add an optional 'snapshot' tag to OS entries

[Zeeshan Ali (Khattak)]

Applications can use this to determine if an OS is just a snapshot and
not an actual released product yet. For example, gnome-continuous images
for development snapshots of GNOME and pre-release and nightly build ISOs
of Fedora etc.
