[PATCH master] logo: Makefile: fix inkscape Wayland GUI opening on LOGO.S

[Ahmad Fatoum]

DISPLAY="" only affects x11 clients. Building sandbox_defconfig under
Wayland will still result in annoying inkscape windows being opened.
Drop DISPLAY = "" in favor of --shell, which should never display
a GUI. --shell has been part of inkscape since 2009 and so should be
generally available.

There is also --without-gui, but that is now deprecated and without
effect. --shell tested working on Inkscape 1.0.1 with both
GDK_BACKEND=wayland and GDK_BACKEND=x11.
