test: guard executable-bit assertions from Windows chmod semantics

The Windows CI job failed because `os.chmod` does not set POSIX
executable bits on Windows, so `install_scripts()` cannot make `.py`/
`.sh` files executable there (nor is it needed — the interpreter is
invoked explicitly). Split the install_scripts test so file-copy
behavior is still verified cross-platform, and skip the executable-bit
assertions on win32 (matching the repo's existing pattern).
