src: fix solaris 10 build error

Stop gcc from getting confused, explicitly cast the return value from
getuid() and getgid() to uint32_t.  Fixes the following build error:

    ../src/node.cc: In function 'void node::GetUid(const
    v8::FunctionCallbackInfo<v8::Value>&)':
    ../src/node.cc:1552:37: error: call of overloaded 'Set(uid_t)' is
    ambiguous
    ../src/node.cc:1552:37: note: candidates are:
    ../deps/v8/include/v8.h:5939:6: note: void
    v8::ReturnValue<T>::Set(bool) [with T = v8::Value]
    ../deps/v8/include/v8.h:5909:6: note: void
    v8::ReturnValue<T>::Set(double) [with T = v8::Value]
    ../deps/v8/include/v8.h:5915:6: note: void
    v8::ReturnValue<T>::Set(int32_t) [with T = v8::Value, int32_t = int]
    ../deps/v8/include/v8.h:5926:6: note: void
    v8::ReturnValue<T>::Set(uint32_t) [with T = v8::Value, uint32_t =
    unsigned int]

Fixes #6182.
stream: objectMode transforms allow falsey values

Closes #6183
handle_wrap: properly don't abort on unwrap

From commit 756ae2c all the WRAP/UNWRAP were moved to a single location
for ease of use. In a single location NO_ABORT should have been used but
wasn't. This caused HandleWrap::Close to abort. Below is the applicable
code change as demonstration there was no abort specified when
unwrapping the object.

 void HandleWrap::Close(const FunctionCallbackInfo<Value>& args) {
    HandleScope scope(node_isolate);

     -  HandleWrap *wrap = static_cast<HandleWrap*>(
     -      args.This()->GetAlignedPointerFromInternalField(0));
     +  HandleWrap* wrap;
     +  UNWRAP(args.This(), HandleWrap, wrap);

Also included a test that will reproduce the abort.
