Fix module dependencies after qt5.git changes

When starting a new round of updates, consider the dependency
information (required, optional) from qt5.git as authoritative, instead
of re-using an existing dependencies.yaml file. This fixes the situation
where after changes to qt5.git a previous optional dependency is not
included in the default set anymore.
