irb2400: Add depend on liblapack-dev to moveit_plugins

Lapack is clearly referenced at https://github.com/ros-industrial/abb/blob/hydro-devel/abb_irb2400_moveit_plugins/CMakeLists.txt#L13

The rosdep key exists at https://github.com/ros/rosdistro/blob/master/rosdep/base.yaml#L1305-L1312

Example build failure: http://csc.mcs.sdsmt.edu/jenkins/job/ros-hydro-abb-irb2400-moveit-plugins_binaryrpm_heisenbug_x86_64/2/console

Thanks,
