qmetatype: Fix incorrect more than one typedef warning

The names are the keys of a hash so they can come in any
order. That means the loop above, which stops before the end if
it finds a name that is not the official one, may not have seen
the official yet. If it has reached the end, then there is no
typedef alias.

Fixes: QTBUG-99620
Pick-to: 6.2 6.3
