Restore advice about making pterm set[ug]id.

cmake doesn't have convincing facilities for doing this in its install
step, so the new advice is to do it manually (we've provided no
equivalent to the autotools --enable-setuid or --enable-setgid options,
nor UTMP_USER/GROUP).

On Unix, pterm would like to be setuid or setgid, as appropriate, to
permit it to write records of user logins to /var/run/utmp and
/var/log/wtmp. (Of course it will not use this privilege for
anything else, and in particular it will drop all privileges before
starting up complex subsystems like GTK.) The cmake install step
doesn't attempt to add these privileges, so if you want user login
recording to work, you should manually ch{own,grp} and chmod the
pterm binary yourself after installation. If you don't do this,
pterm will still work, but not update the user login databases.
