test(e2e/47): strip trailing CR from jq output on git-bash/Windows

The Windows CI run reported:
  FAIL: basename is not pcm.cache/gcm.cache: 'pcm.cache
  '
The closing quote on the next line is the giveaway — the value carries a
trailing `\r`. `jq.exe` on git-bash emits CRLF; `mapfile -t` strips LF
but leaves CR, so every downstream comparison saw `pcm.cache$'\r'` and
failed. Trim with `${v%$'\r'}` per element.

The source-code fix (un-escape ninja sequences) is working — the value
itself is now a clean `C:\Users\...\pcm.cache`, no `$:` artefact.
