rootfs_ipk.bbclass: always specify tmp_dir in opkg-cl call with -t parameter

* When option tmp_dir is used in opkg.conf installed on rootfs then it's
  used also in do_rootfs call and points to probably non-existent directory
  on buildhost like /var/lib/opkg/tmp.
* The value of tmp_dir from rootfs is used even with another config file
  specified with -c parameter
* Before this, it was using default value (/tmp) on buildhost, now it will use
  own "${IMAGE_ROOTFS}-tmp" and remove it after do_rootfs finish
  (usually already empty inside, cleaned by opkg itself)
* Similar patch for testlab.bbclass will follow
