opkg: enable libsolv backend by default

The libsolv backend is vastly superior than the currently enabled
internal ad-hoc solver. While the switch does have a small impact on
disk and memory footprint, it make sense to change the default as for
most cases the disk/memory footprint hit should be acceptable.
