Subject: CarpetIOASCII: Correct handling of "output_symmetry_points"

Only apply the parameter output_symmetry_points at outer boundaries.

Only apply the parameter out3D_outer_ghosts if this is not a symmetry
boundary.

Unify handling of output_symmetry_points, out3D_ghosts, and
out3D_outer_ghosts.
