Both shadercache and compatdata are required to count as sync-able

[Desdaemon]

I was looking into why CryoUtilities wasn't syncing any of my compatdata from internal storage to the SD card, and I came across these lines:

https://github.com/CryoByte33/steam-deck-utilities/blob/db020c24bb74428b4f60d525e346ac6d2eb6f7b9/internal/handler_game_data.go#L175-L177

I then double-checked that my shadercache is empty since I must have disabled it some time ago. Would it be possible to sync games if they only have compatdata? Thanks for your hard work!

Note: For anyone running into this issue, here's a temporary fix:

cd ~/.local/share/Steam/steamapps
mkdir shadercache
cd shadercache
for f in $(ls ../compatdata); do mkdir $f; done
