fix names for more packages
Now x11-packages repository will use original names for
packages. For example, libgtk2 now will be provided as
gtk2, libgtk3 will be available as gtk3, libsdl - as sdl.

List of changed packages:

 libatk        --> atk
 libglu        --> glu
 libgtk2       --> gtk2
 libgtk3       --> gtk3
 libmesa       --> mesa
 libsdl        --> sdl
 libsdl2       --> sdl2
 libsdl-net    --> sdl-net
 riscvemu-sdl  --> riscvemu
 xorg-xvfb     --> xorg-server-xvfb

List of dependent packages (should be rebuilt with new deps):

 dosbox, emacs-x, galculator, geany, libepoxy, mtpaint,
 qemu-system-x86_64, the-powder-toy, tigervnc, wireshark-gtk,
 xarchiver.

Note: depending on which packages are installed, it may be
necessary to upgrade with 'apt dist-upgrade'.
