Django 3.1.9 fixes a security issue in 3.1.8.

## CVE-2021-31542: Potential directory-traversal via uploaded files

`MultiPartParser`, `UploadedFile`, and `FieldFile` allowed directory-traversal via uploaded files with suitably crafted file names.

In order to mitigate this risk, stricter basename and path sanitation is now applied.
