[Libosinfo] [libosinfo PATCH v4 08/10] loader: Load Images information

[Fabiano Fidêncio]

Now that we've OsinfoImage and OsinfoImageList objects in place and
OsinfoOs already provides us an API to add an OsinfoImage to an
OsinfoOS, let's properly load the images' information present in
osinfo-db.
