Reimplement QAbstractFileEngine::open() properly

The virtual function takes a QIODevice::OpenMode argument, not an int.

tests/auto/corelib/io/qfile/test/../tst_qfile.cpp:1942: warning:
'MyEngine::open' hides overloaded virtual function [-Woverloaded-
virtual]
    bool open(int ) { return false; }
         ^
src/corelib/io/qabstractfileengine.h:118: hidden overloaded virtual
function 'QAbstractFileEngine::open' declared here
    virtual bool open(QIODevice::OpenMode openMode);
                 ^
