[PATCH v3 4/5] selftest/bpf: Enable verifier selftest for powerpc64

[adubey at linux.ibm.com]

From: Abhishek Dubey <adubey at linux.ibm.com>

This patch enables arch specifier "__powerpc64" in verifier
selftest for ppc64. Power 32-bit would require separate
handling. Changes tested for 64-bit only.
