perf cs-etm: Use new OpenCSD consistency checks

Previously when the incorrect binary was used for decode, Perf would
silently continue to generate incorrect samples. With OpenCSD 1.5.4 we
can enable consistency checks that do a best effort to detect a mismatch
in the image. When one is detected a warning is printed and sample
generation stops until the trace resynchronizes with a good part of the
image.
