[Libosinfo] [libosinfo PATCH] tree: Add "os" property

[Fabiano Fidêncio]

Similarly to what we have for media, let's add the "os" property to the
trees.

osinfo-detect code is already relying on having an "os" property and,
since commit 722e7d1d4, it errors out due to the missing property:

(osinfo-detect:7808): GLib-GObject-WARNING **: 09:27:58.656: g_object_get_is_valid_property: object class 'OsinfoTree' has no property named 'os
