selftests/powerpc: Add more utility macros

Browse source 
Adds _MSG assertion variants to provide more context behind why a
failure occurred. Also include unistd.h for _exit() and stdio.h for
fprintf(), and move ARRAY_SIZE macro to utils.h.

The _MSG variants and ARRAY_SIZE will be used by the following
DEXCR selftests.
