selftests/powerpc: Use "Delta" rather than "Error" in normal output
Use "Delta" to refer to the difference between measurements, rather than
"Error", so scripts that look for "Error" aren't confused into thinking
there was a failure.

selftests/powerpc: Run EBB tests only on POWER8
EBB (Event Based Branches) are currently only available on POWER8, so we
should skip them on other CPUs.
I've found that at least one test loops forever on 970MP (cycles_with_freeze_test).
