r4501: when copying files it is common for clients to copy the ACL. When the
ACL is the default ACL this menas the copied file would have an xattr
but the original would not. Avoid this by checking if the ACL being
set is the original ACL, and avoid the copy.
(This used to be commit 1df985a49b200a41eed39023aa668afb233f2e53)
