tutorials/lagrangian/reactingParcelFoam/splashPanel: Resolved divergence

The side surfaces in this tutorial have been made symmetry planes to
match the corresponding boundaries in the film region, and the top has
had its pressure condition changed to totalPressure. The case now runs
successfully to completion.

Previously the pressure-velocity boundary condition combination on the
non-film patches was incorrect in that in regions of outflow a pressure
value was not being specified. This resulted in divergence.
