[COMMITTED] ada: Remove redundant guard against an empty list of interfaces

[Marc Poulhiès via Gcc-patches]

From: Piotr Trojanek <troja...@adacore.com>

Code cleanup; semantics is unaffected.

gcc/ada/

        * sem_type.adb (Iface_Present_In_Ancestor): Remove guard for empty list
        of interfaces; the following loop will work just fine without it.

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