files: ignore errors when calling futimens() on a backup file
Access control lists can permit read and write access to a file but not permit to manipulate any attributes of the file. So it is quite possible for futimens() to fail, just like chown() and chmod() can fail, but this should be no cause for alarm: as long as writing the backup file worked, then writing the file itself will probably work too.master
