mi_load_progress: Use unique_ptr to manage ui_out lifetime

Browse Source 
In mi_load_progress, we xfree a ui_out object.  Because ui_out is not
trivially destructible, it should be freed with delete.  This patch
makes use of a unique_ptr to do it.

gdb/ChangeLog:

	* mi/mi-main.c (mi_load_progress): Make uiout variable
	a unique_ptr.
