Cygwin: fix permission problem when writing DAC info on Samba shares 

Cygwin always requests FILE_WRITE_ATTRIBUTES permissions when trying to
change DAC information.  This can lead to permission problems when
trying to chmod/chown files on Samba shares.  Drop requesting
FILE_WRITE_ATTRIBUTES on Samba shares and go with WRITE_DAC/WRITE_OWNER
only.
