shiboken6: Fix crash when using enumeration types from other classes

qtbase/969337bcfd6af6d91b988e4b412703274a0b5877
changed QHostAddress to use enum values from QAbstractSocket which
appear as fields. This caused a crash in the module initialization
since QAbstractSocket was not initialized when creating the field
entries. Consider this in the dependency calculation.
