sigproc: Adjust burst detection threshold criteria

Reduce the burst detection threshold to pass more bursts to upper
layers, but force stricter requirements on the computation itself.
For the latter, we now require at least 5 samples (rather than 2)
to compute a peak-to-average value.

End result is increased burst detection at low SNR conditions with
a small increase in false positive bursts when no signal is present.
