Fixed dylib generation on macOS

We just build libSDL3.dylib instead of libSDL3.0.0.0.dylib with symlinks

Fixed the compatiblity vs current version, e.g.

SDL 3.20.87
    @rpath/libSDL3.0.dylib (compatibility version 2001.0.0, current version 2001.87.0)

SDL 3.21.5
    @rpath/libSDL3.dylib (compatibility version 2106.0.0, current version 2106.0.0)
