Subject: [PATCH] Add unistd.h required for getuid().

Without this, we get the following build failure:
```
tensorflow/tools/graph_transforms/transform_graph.cc: In function 'std::__cxx11::string tensorflow::graph_transforms::ExpandPath(const string&)':
tensorflow/tools/graph_transforms/transform_graph.cc:150:36: error: 'getuid' was not declared in this scope
       struct passwd* pw = getpwuid(getuid());
                                    ^~~~~~
tensorflow/tools/graph_transforms/transform_graph.cc:150:36: note: suggested alternative: 'getpwuid'
       struct passwd* pw = getpwuid(getuid());
                                    ^~~~~~
                                    getpwuid
```
