Martin Weinelt b01149720f file: relax landlock sandboxing for tar.bz2 compat
The new landlock sandbox does not allow executing any programs under /,
which prevents it from executing the bzip2 helper to determine the
correct mime type response.

```
$ touch foo
$ tar -cjf foo.tar.bz2 foo
$ file --brief --mime --uncompress foo.tar.bz2
application/x-decompression-error-bzip2-Cannot-posix-spawn--bzip2---Permission-denied compressed-encoding=application/x-bzip2; charset=binary`
```
