[Bug 2006483] [NEW] Fails autopkgtests when tested against fuse3 >= 3.13

[Lukas Märdian]

Public bug reported:

The autopkgtest in `tests/test-rofiles-fuse.sh` (executed via `gnome-
desktop-testing-runner libostree/test-rofiles-fuse.sh.test`) fails to
execute `setfattr -n user.foo -v bar mnt/anewfile-for-fuse` with the
error message "setfattr: mnt/anewfile-for-fuse: Numerical result out of
range".

It's unclear if this is related to glibc, FUSE_USE_VERSION, kernel fuse
protocol or another component.

On Debian this specific test is skipped, due to missing the "capsh" binary (libcap2-bin) in the test env:
```
/usr/libexec/installed-tests/libostree/libtest.sh: line 688: capsh: command not found
1..0 # SKIP No cap_sys_admin in bounding set, can't use FUSE
```

The relevant log (inside an Ubuntu autopkgtest qemu runner) is provided
here:
