On darwin, only add the self exe to the cache hash for compiler id (#5880)
Now that Big Sur does not have system libraries on the filesystem, zig can no longer read them and add them to the cache hash for the compiler id. This changes it so that only the first library path returned by os_self_exe_shared_libs is added to the cache hash under Darwin. I looked into methods on getting the system version to keep parity with older versions, but @fengb reported that this works on Catalina (a version behind Big Sur) Signed-off-by: Haze Booth <isnt@haze.cool>
