Fix Q_BASIC_ATOMIC_INITIALIZER for std::atomic

We can't have too many braces: one pair is just enough because we're
actually calling the QBasicAtomicInt's constructor. That is, we're using
the uniform initialization procedure.

Required for Clang 3.7:
qmetatype.h:1772:46: error: braces around scalar initializer [-Werror,-Wbraced-scalar-init]
        static QBasicAtomicInt metatype_id = Q_BASIC_ATOMIC_INITIALIZER(0);
                                             ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
qatomic_cxx11.h:331:43: note: expanded from macro 'Q_BASIC_ATOMIC_INITIALIZER'
#define Q_BASIC_ATOMIC_INITIALIZER(a)   { {a} }
                                          ^~~
