MiniVMac.cc: Preserve attributes when copying

When copying files from the system disk image to the new disk image,
preserve all attributes (creation date, modification date, bundle bit,
locked bit, etc.), except clear the inited bit so that the Finder
chooses new icon positions, otherwise (under System 6 at least) the
icons pile up on top of each other. Preserving the bundle bit in
particular tells the Finder to look in the file for icon information
when building the desktop database, without which the files all show
generic icons in the Finder.
