Add support for osinfo_filter_add_constraint() OR filter
Currently,
osinfo_filter_add_constraint (filter, prop_x, value1)
osinfo_filter_add_constraint (filter, prop_x, value2)
filters based on prop_x == value1 && prop_x == value2
We need to add OR based filtering
filters based on prop_x == value1 || prop_x == value2
E.g.
installer_profile == "jeos" || installer_profile == "desktop"
