[BotW] Fix weather pack for legacy code patching

Browse Source 
This uses a workaround for Cemu's legacy patching (so the backwards compatibility that Cemu provides for patches.txt file, and now defaults too even if Cemuhook is found) not allowing one to have symbols that refer to a memory address that's outside of the game's own executable memory.
