libredirect: build fat library for x86_64, arm64, arm64e on darwin (#153441)

Browse Source 
macOS's dyld can be rather picky as to what dylib it accepts. This
even changes across macOS versions. Therefore we now build a fat
dylib with all three architectures (x86_64, arm64, arm64e). This
should then be compatible with pretty much any macOS's dyld.
