[qmp-system] Migrate to new UCI network model (II)

Add the qmp_uci_get_raw_item_space_filter_by_name() function to
complete the qmp_uci_get_item_by_unnamed_section_type_and_name()
function, which would otherwise incorrectly return the items for
all the unnamed sections of a given class, instead of just the one
filtered by its "name" property value.

Fixes #489.
