[tlbuild] dvisvgm error with LLVM/Clang

[Karl Berry]

    compiler is LLVM/Clang.
    ...
    ../../../texk/dvisvgm/dvisvgm-1.9/src/VectorIterator.h:100:8: error:
    reference to non-static member function must be called
                            if (valid)

As you suggest, presumably the solution is to use valid(), as is done in
the other occurrences.

Martin, does it look ok?
