Emi Matchu b1f06029f8 Moderize RocketAMF C types to fix build error
I'm not sure if this is a Mac-only problem or what, but we were getting incompatible-function-pointer errors when trying to build the RocketAMF C extensions. This fixes that! (Maybe it's like, Mac-only but as of Ruby 3.4 in specific? We're running RocketAMF in production on Ruby 3.4 right now without this. Shrug.)
