st: Use consistent type for properties/getters

gjs now optimizes property accesses if possible, by calling the
corresponding getter/setter method. For this to work, the method
not only has to exist (obviously), but also match the type of
the corresponding property.

Both `Label` and `Entry` currently define their `clutter-text`
property as `Clutter.Text`, while the corresponding getter
returns the more generic `Clutter.Actor`.

Fix that so that both property and getter use the more specific type.
