package_manager.py: respect OPKGLIBDIR
* respect it for incremental rootfs generation
* add lists_dir option to opkg.conf
* also fix setting info_dir and status_file when they use default value, the
problem is that self.opkg_dir is already prefixed with rootfs directory,
comparing it with /var/lib/opkg always returned false and the options were
appended to config file unnecessary
* with opkg 0.3.4 we can use VARDIR prefix added in:
