Fix an array initialization.

GCC 4.8 complains about the brace initialization:

./source/grid/manifold_lib.cc:1804:75:
warning: missing initializer for member 'std::array<double, 12ul>::_M_elems'
[-Wmissing-field-initializers]
         std::array<double, GeometryInfo<3>::lines_per_cell> weights_lines{};
                                                                           ^

so be safe and initalize explicitly with fill.
