itemize() needs to use CHMOD_BITS (patch)

[Roderick Schertler]

When syncing from Linux to Aix --itemize-changes with --perms lists
directories every time because the high-order st_mode bits for
directories differ between the two systems, and itemize() isn't masking
them with CHMOD_BITS.  Here is a fix, tested with 2.6.6pre1.
