tigervnc: Add Xvnc

Xvnc is the X.org xserver with a framebuffer display (like Xvfb) but
adapted by tigervnc to offer the framebuffer via the vnc protocol.

Build instructions :

https://github.com/TigerVNC/tigervnc/blob/7cc9f6ad07db1f4f7f141d229d2dc5035bd2f89d/BUILDING.txt#L97

Some configure option suggested by the above instructions are not
recognized by the x.org xserver 1.19.6 configure script and removed:

    --disable-config-dbus
    --enable-install-libxf86config
    --with-fontdir
    --with-dri-driver-path

The option --disable-xwayland has been added to avoid the creation of
/usr/bin/Xwayland conflicting with the xorg-server package.

Installation of a Xserver manpage has been disabled for the same
reason.
