Fix headergenerator to build under C++11

For a long time, headergenerator.cpp did only generate destructors,
when the following condition was set:

if (!avoidProtectedHack() || !metaClass->hasPrivateDestructor()) {
    // generate destructor
}

The condition does not work for C++11.

When trying to remove the protected hack, I remembered that
I used an ugly CMake trick to make VS 2015 work. This hack
provided exactly the missing destructors.
I tried very hard to make this hack into a patch for Linux and
macOS, too. Unfortunately, when built without the protected hack,
Clang enforces a destructor declaration, but then the linker reports
an unresolved symbol. I have found no way to circumvent this.

Conclusion: Unless we find a way to make Clang work correctly,
we have to leave the protected hack as-is on macOS.
But then, the whole effort of hack removal makes no more sense.
Fortunately, the ugly work-around on Windows is gone, now.

So this change involves shiboken and PySide, and probably the one
will not work without the other.
