Qulqy (plyr0, BSD-3-Clause), commit 6d1e676: build without the GB Compo 2025 logo screen.

The game opens on the GB Compo 2025 logo (a third-party mark) and waits for Start. This patch drops
the screen: the show_splash() call and its waitpad(), the function itself and the logo object in the
Makefile. build-qulqy.sh also deletes the logo files (src/res/gbcompo2c.c/.h, res/gbcompo2c.png,
res/old/gbcompo2.png, res/png.txt).

The logo screen was also the only wait between power-on and loading a saved game, and that load
seeds the random generator with clock(). Without the wait the seed of a resumed game would be the
same on every power-on, so the patch reseeds once on the first move after loading. Nothing else
changes.
