[FEATURE] use --fatal-errors for aplay/arecord tests #1120

Is your feature request related to a problem? Please describe.
When we reach an xrun, we should stop sof-test scripts. xruns need to be recoverable, but they should never happen. we don't want to miss these issues because the recovery quicks-in and hides problems.

Describe the solution you'd like
Add --fatal-errors to aplay/arecord command-line options.

Example run with --test-position (needs aplay patch to dump the last result)

Status(R/W) (standalone avail=36 delay=924):
  state       : RUNNING
  trigger_time: 2045.504937
  tstamp      : 2190.754602
  delay       : 924
  avail       : 36
  avail_max   : 444
Status(R/W) (standalone avail=44 delay=912):
  state       : RUNNING
  trigger_time: 2045.504937
  tstamp      : 2190.754852
  delay       : 912
  avail       : 48
  avail_max   : 48
underrun!!! (at least 471.161 ms long)
Status:
  state       : XRUN
  trigger_time: 2190.786234
  tstamp      : 2191.257392
  delay       : 0
  avail       : 1412
  avail_max   : 1412
aplay: xrun:1690: fatal underrun: Success

Describe alternatives you've considered
none that I can think of

Additional context
Not sure if we want to add this in sof-test proper, or add this in the environment variables with "APLAY_OPTS" that are already supported.
