[Ada] Warnings on g-spogwa.adb

[Pierre-Marie de Rodat]

This unit added recently generate legitimate warnings which were not
caught because this file had not been added to Makefile.rtl.

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

gcc/ada/

        * Makefile.rtl (GNATRTL_NONTASKING_OBJS): Add g-spogwa object.
        * libgnat/g-spogwa.adb: Fix style errors.
