Fix C++ ow binary to produce translations

- Node::mark and Node::score uninitialized, causing segfaults in
  topological_sort — add default initializers (0, 0.0)
- odenwald.cc called incomplete sv_path() + exit(1) instead of
  viterbi_path()
- viterbi_path: add reset() before topological_sort, initialize
  best_edge to nullptr
- derive: off-by-one in NT order indexing — start j at 1 and
  use order[j]-1 (1-indexed alignment map)
- read: ifs.readsome() returns 0 on macOS — use ifs.read() +
  ifs.gcount()
- manual() signature: add missing Vocabulary parameter
- Remove gperftools/tcmalloc dependency from Makefile
