dpp,dpp-util: cast size_t for constant arguments to va_arg

Browse Source 
There were a few places in dpp/dpp-util which passed a single byte but
was being read in with va_arg(va, size_t). On some architectures this was
causing failures presumably from the compiler using an integer type
smaller than size_t. As we do elsewhere, cast to size_t to force the
compiler to pass a properly sized iteger to va_arg.
