Description

tests: stabilize test-persistent-nodemap.t on Windows

Several issues here:

  • Hooks can't invoke shell scripts on Windows, so use sh to launch
  • dd in MSYS only recognizes status=noxfer
  • The PATH updating triggered a massive slowdown, but is no longer needed

I have no idea why, but removing the PATH update substantially increased the
speed of the test. It was running finishing at ~4:30 with --debug and ~14:50
without it, but now completes in ~2:20 on my Windows laptop.
