chap-x.xml: update the Xfce4 example

The Xfce4 example was about a decade out of date. Update to make it
more current, and also to suggest that (as with many things NetBSD/
pkgsrc) choice can be involved, rather than just telling users to
"turn everything on to make it work". (I don't run it with system-wide
dbus or polkit in use, as I have no need to, and I know I'm not alone.)

Xfce4 dropped fam and hal a while ago. That also makes rpcbind
unneeded, as it was in turn a dependency of fam. (I see that fam is
still listed as a dependency of kcoreaddons, curiously.) Optional
Polkit support was added (which is a suggested/default option in
pkgsrc).

(While ConsoleKit is used by MATE to determine settings for power
control, presently Xfce4 instead first uses a hard-coded approach in
xfce4-session that assumes if it's running on a BSD, "operator" is the
required group that enables the requisite permissions, without user
configurability otherwise. If that check fails, then it falls back to
trying via Polkit, assuming that functionality has been compiled in.
Here I've just mentioned that "operator" group membership is the norm.
Separate details about Polkit could perhaps be added.)

The first pass at addressing PR pkg/55209 from Samuel Marks. (There
could be further room for improvement, though I don't want to turn
that section into a detailed how-to guide for Xfce4.)
