Make sure that POOL_IMPORTED is set, unset and checked where appropriate.
* If it's unset in find_rootfs(), no pool is imported so no point in
looking for a rootfs.
* If find_rootfs() couldn't find a rootfs, the pool is exported. Remember
to unset POOL_IMPORTED after doing so.
* Set POOL_IMPORTED if/when a pool have been imported in import_pool().
* Improve backup import (the one using cache file).
