fix compilation error in compute_ghost_cell_halo_layer

Fix the following compilation error on my machine (gcc 4.6.3)

/ssd/deal-git/source/grid/grid_tools.cc:1581:103: error: no matching
function for call to ‘compute_active_cell_halo_layer(const
dealii::Triangulation<1, 1>&,

/ssd/deal-git/source/grid/grid_tools.cc:1581:103: note: candidate is:

const std::function<bool(const typename
Container::active_cell_iterator&)>&)
