Fix crash when scrolling using touchpad on macOS 10.6 (I fixed it in SDL 2.0.18) and fix failing to start on x86 due to ioq3 SDL dylib having absolute path instead of "@executable_path/libSDL2-2.0.0.dylib". SDL 2.24.0 removed macOS 10.6 support (last with x86). Offically at least, they also dropped x86_64 on macOS 10.7 and 10.8. So ioq3 UB1 is limited to SDL 2.0.22. - Update x86 and x86_64 to SDL 2.0.22. Compiled with 10.13 SDK as 10.14 SDK dropped running on older than macOS 10.9 and I ran "strip -x" on the libraries. Ad-hoc signed with PyOxidizer rcodesign. - PPC is still MAN-AT-ARMS' SDL 2.0.1 build but I ran "strip -x" on it to reduce the file size. - ARM64 build was removed from UB1 as UB2 with SDL 2.24.0 should be used instead.
