journal: move the gist of server_fix_perms to acl-util.[hc]
Most of the function is moved to acl-util.c to make it possible to add tests in subsequent commit. Setting of the mode in server_fix_perms is removed: - we either just created the file ourselves, and the permission be better right, - or the file was already there, and we should not modify the permissions. server_fix_perms is renamed to server_fix_acls to better reflect new meaning, and made static because it is only used in one file.
