Subject: [PATCH 71/74] perf script: Remove workqueue-stats script

From: Tom Zanussi <tom.zanussi@linux.intel.com>

The tracepoints used by the workqueue-stats script no longer exist so
trying to run the script results in:

  # perf script record workqueue-stats
  invalid or unsupported event: 'workqueue:workqueue_creation'
  Run 'perf list' for a list of valid events

So remove the script until it can be reworked using the new workqueue
tracepoints.
