selftests: vDSO: fix vdso_config for powerpc

Running vdso_test_correctness on powerpc64 gives the following warning:

~ # ./vdso_test_correctness
Warning: failed to find clock_gettime64 in vDSO

This is because vdso_test_correctness was built with VDSO_32BIT defined.

__powerpc__ macro is defined on both powerpc32 and powerpc64 so
__powerpc64__ needs to be checked first in vdso_config.h
