yabai: remove Mach-O UUIDs

Darwin ld emits LC_UUID by default. yabai also embeds the
scripting-addition payload and loader binaries into the final
executable, so UUIDs from those intermediate Mach-O files make rebuilds
differ.

Pass -Wl,-no_uuid through the existing clang substitution so the main
binary and embedded OSAX binaries are deterministic.
