When instantiating generic package that includes a formal subprogram
declaration with Ghost aspect and a subprogram_default of null, e.g.:
generic
with procedure Proc is null with Ghost;
package P is ...
the Ghost aspect should be propagated to the internally generated null
subprogram, so this null subprogram can be used in contexts that require
ghost entities.
