[PATCH v5 2/2] selftests/bpf: Enable private stack tests for powerpc64

[adubey@linux.ibm.com]

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

With support of private stack, relevant tests must pass
on powerpc64.

#./test_progs -t struct_ops_private_stack
#434/1   struct_ops_private_stack/private_stack:OK
#434/2   struct_ops_private_stack/private_stack_fail:OK
#434/3   struct_ops_private_stack/private_stack_recur:OK
#434     struct_ops_private_stack:OK
Summary: 1/3 PASSED, 0 SKIPPED, 0 FAILED

v4->v5:
  Rebase over latest branch
v3->v4:
  No change
v2->v3:
  Enable testcase using __powerpc64__ instead of __TARGET_ARCH_powerpc,
  to prevent it getting invoked on powerpc32
v1->v2:
  No change
