Benchmarks: Xenomai dual-kernel over Linux 3.10.18

In this fifth benchmark, like for the third, we simply compare latencies with the previous kernel, and observe that there is no regression. We removed the OMAP5 µEVM board, as its port was never finished, and had an issue with unlocked context switch enabled.

Measurement method

The measurements were done with the xeno-test utility, see the Benchmarking with xeno-test page for details.
