[S390] hwsampler: Set a sane default sampling rate
The sampling interval for the hardware sampler is specified in cycles. (see SA23-2260-01 The Load-Program-Parameter and the CPU-Measurement Facilities) The current default value will therefore result in millions of samples. This patch changes the default sampling interval to 4M, which will result in ~1500 samples per second on a z196 reducing the overhead of sampling.
