ada: Fix internal error on aggregate within container aggregate

This just applies the same fix to Expand_Array_Aggregate as the one that was
recently applied to Convert_To_Assignments.

gcc/ada/
	PR ada/118234
	* exp_aggr.adb (Convert_To_Assignments): Tweak comment.
	(Expand_Array_Aggregate): Do not delay the expansion if the parent
	node is a container aggregate.
