gh-96005: Handle WASI ENOTCAPABLE in getpath (GH-96006)

Browse source 
- On WASI `ENOTCAPABLE` is now mapped to `PermissionError`.
- The `errno` modules exposes the new error number.
- `getpath.py` now ignores `PermissionError` when it cannot open landmark
  files `pybuilddir.txt` and `pyenv.cfg`.
