Fix python search path in emsdk launcher scripts (#1571)

The `-0` and `-1` suffixes here are not part of the install path which
only based on the `id` and `version` of the tool. e.g:

```
  {
    "id": "python",
    "version": "3.9.2",
    "bitness": 64,
    "arch": "x86_64",
    "windows_url": "python-3.9.2-1-embed-amd64+pywin32.zip",
    "activated_cfg": "PYTHON='%installation_dir%/python.exe'",
    "activated_env": "EMSDK_PYTHON=%installation_dir%/python.exe"
  },
```

Here we have a `-1` in the archive name, but that is not included in the
version which is used to construct the install path.
