utils/latmus: restrict C-state when applicable
...
If /dev/cpu_dma_latency is present, we can restrict the usable C-state
the CPU may be asked to enter by writing zero to this file, and
keeping the file descriptor open for the duration of the test. This
helps in preventing PM-originated latency spikes.

utils/latmus: run sampler on a CPU from the OOB set
...
If -c was not given, we must run the sampler on a CPU which is part of
the out-of-band set the core is controlling since such set might have
been restricted on the kernel command line (i.e. evl.oobcpus=).

utils/latmus: include results from the last bulk
...
When the test is interrupted, we usually have some results pending in
kernel space which have been collected but not yet received via the
cross-buffer. Make sure to collect and include them in the latency
report.
