[PATCH 3/4] oeqa.buildperf: treat failed measurements as errors

[Markus Lehtonen <markus.lehtonen@linux.intel.com>]

Now failed measurements correctly cause a test failure (recorded as an
error). There should be no need to continue the test if one step fails,
especially now that the tests don't depend on each other.
