These have been:
- taken from x86_64 server iso (in substituted form);
- checked against m-p-d where needed;
- renamed from centaurus-* to centaurus/*;
- updated with s/samba-server/samba/;
- archdep bits adjusted for m-p-d/m-p syntax difference;
- amended with some tester feedback based additions included;
- pruned regarding p9/branch packages availability.

...following another inspection of m-p-d's centaurus pkglists.

Non-GUI packages moved to base+nm pkglist to enable standalone
installation of those; and GTK bits left in desktop+nm for use
by images lacking their own new and improved(tm) variant.

Note that both GNOME3 and KDE4 aren't lacking anymore.

For MATE regular images right now
but should be more widely useful.
