Remove dead ValueOfMaterialInTroubleAfterNull

Declared in chess.h, defined in dynamic.c, documented as the
nullmove-pruning safety-net sibling of ValueOfMaterialInTroubleDespiteMove
-- but it had zero call sites anywhere in the tree, only a comment in
search.c describing what it was conceptually meant to catch. Nothing
ever wired it in.
