Fix use of QMutex on Linux before FUTEX_PRIVATE_FLAG was added
It was added in 2.6.22. If we pass it to 2.6.21, we'll get -ENOSYS,
which is bad for QMutex. This fix simply defines it to 0 if the header
doesn't define it.
But as a consequence: if Qt is built with newer kernel headers, it won't
run on older versions. It's not likely that someone is still using Qt
5.7 on a 2.6.21 kernel (v2.6.21.7 was released on 2007-08-04).
