Fix breakage due to meta-type id reordering in qtbase

Commit aee1f6cc413f56bf4962324799ee3887c3dd037f in qtbase changed the
order/IDs of the "extended" meta-types, so that they are not
bigger than QVariant::UserType (127) anymore. This caused autotests
in qtdeclarative to assert/fail.

Ths commit adapts the logic in qtdeclarative accordingly, in
particular so that QVariant/QObjectStar aren't treated as value
types.
