Parts of the `dbus-appinfo` test need support for converting an FD to a
path, and Hurd doesn’t currently allow that (see
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/4396#note_2279923).
Since there’s no fix for that visible in the medium term (new kernel
APIs will need to be added), skip parts of the `dbus-appinfo` test which
require that functionality for now.
This prevents the whole test from failing, and means we can usefully get
results from the parts of it which don’t depend on converting FDs to
paths.

This could potentially eventually become a public GLib API, but there
doesn’t seem to be a huge need for it right now (e.g. this file contains
the only use of `/proc/self/fd/%d` in GLib), so let’s keep it private
for now and avoid committing to API stability just yet.
This gives time for other platforms to add their platform-specific
implementations for it too, if they need. I’ve added a couple of
pointers to what I *think* the right APIs might be, from my research,
but I have not prototyped those implementations.
