[Ada] Adjust support for 128-bit integer types in System.Random_Numbers

While the default function returning 128-bit integer works correctly,
Random_Discrete does not if it is instantiated on a 128-bit integer,
since the magnitude of the returned numbers is still 64 bits.

Note that no counterpart is needed in GNAT.Random_Numbers because the
homonymous function in there is just a forwarder for the original one.

Tested on x86_64-pc-linux-gnu, committed on trunk

gcc/ada/

	* libgnat/s-rannum.adb (Random_Discrete): Specifically deal with
	the case where the size of the base type is larger than 64 bits.
