Remove a redundant QT_VISIBILITY_AVAILABLE check. Pointed out by Thiago
in review.
Note that this is going to help with breaking include cycles between
qglobal.h and qcompilerdetection.h (otherwise we'd have to include
qtconfiginclude.h in qcompilerdetection.h as the former includes
qconfig.h which defines QT_VISIBILITY_AVAILABLE; without
QT_VISIBILITY_AVAILABLE defined, Q_DECL_EXPORT/IMPORT expands to
nothing on Linux and co., and tools linking to qtcore (with bootstrap)
can't find exported methods.
