Fix other `-pixel` musicSuffixes not using RetroCameraFade
Description
The special retro fade-out/fade-in for pixel Game Overs only happens for bf-pixel because musicSuffix has to be exactly equal to '-pixel', which other characters, like say, pico-pixel, can't use without sharing the default Game Over theme. This fixes that so that the retro fade-outs can play with different -pixel musics.

Honestly wish pixel related stuff like this wasn't hard-coded. Never understood why that was done, it wouldn't be very hard to do me thinks
yeah thats true
