powerpc/sstep: Fix emulate_step test if VSX not present 



emulate_step() tests are failing if VSX is not supported or disabled.

  emulate_step_test: lxvd2x         : FAIL
  emulate_step_test: stxvd2x        : FAIL

If !CPU_FTR_VSX, emulate_step() failure is expected and testcase should
PASS with a valid justification. After patch:

  emulate_step_test: lxvd2x         : PASS (!CPU_FTR_VSX)
  emulate_step_test: stxvd2x        : PASS (!CPU_FTR_VSX)
