Be more tolerant with multiple differerent metatype registrations

There is a qFatal in qmetatype.cpp that checks that the flags are the same.

There is a binary compatibility break because if any cause build with Qt 5.5
is loaded, this qFatal will quit the application, due to the change in
commit 54a09a41885e65fea4ca20d0e3d90d8f4e9e80c5:

  Type flags for type 'QtMetaTypePrivate::QPairVariantInterfaceImpl' [1034]
  don't match. Previously registered TypeFlags(0x103), now registering
  TypeFlags(0x107). This is an ODR break, which means that your application
  depends on a C++ undefined behavior.

This is a false positive since it is an internal type, the MovableType in
QMetaType is only being used for performance reason, it is perfectly fine
to change it.

This commit changes the qFatal to complain only about flags that could
only be caused by a binary incompatible change.
