Subject: [PATCH] tests/file: Do not rely on du --bytes behaviour
As explained in the previous commit, GNU Coreutils 9.2 changes the behaviour
of `du --bytes` to only count regular files and symlinks.
The previous commit makes the test pass with GNU Coreutils >=9.2, but the
machine running the tests may have an older version, or perhaps even a
reimplementation such as uutils. So we can't rely on the size returned by `du`
to be the consistent across systems any more.
However, the plus side of the new behaviour is that the size reported by `du`
/ `G_FILE_MEASURE_APPARENT_SIZE` is now well-defined across filesystems
(as the sum of the sizes of regular files & symlinks), so we can hardcode it.
Fixes: https://gitlab.gnome.org/GNOME/glib/-/issues/2965
