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.

$ hg init a
$ cd a
$ touch a; hg commit -qAm_
$ hg bookmark $(for i in $($TESTDIR/seq.py 0 20); do echo b$i; done)
$ hg clone . ../b -q
$ cd ../b
Checking that when lookup multiple bookmarks in one go, if one of them
fails (thus causing the sshpeer to be stopped), the errors from the
further lookups don't result in tracebacks.
