1. Change name of discord's library to libdiscord_game_sdk, so it
links properly
2. Change it's install name with install_name_tool to use @loader_path
instead of @rpath, that one's a blunder on discord's side, it should
really have been loader_path from the beginning (rpath means look at
where the binary is started from, loader_path means look at where the
library is)
3. Combine the aarch and x86 library into one, again no idea why
discord does not do this themselves
