[COMMITTED] ada: Remove redundant calls in handling of aspect specifications

["Marc Poulhiès" <poulhies@adacore.com>]

From: Piotr Trojanek <trojanek@adacore.com>

Routine Set_Aspect_Specifications sets the Has_Aspect flag, so there is
no need to set this flag again afterwards.

Code cleanup; semantics is unaffected.

gcc/ada/

	* aspects.adb (Relocate_Aspect): Remove call to Set_Has_Aspects.
	* sem_ch12.adb (Analyze_Formal_Package_Declaration): Likewise.
	* sem_util.adb (Copy_Ghost_Aspect, Copy_SPARK_Mode_Aspect):
	Likewise.

Tested on x86_64-pc-linux-gnu, committed on master.
