Revert "Unix compatibility mode" in File::Copy on VMS.

This backs out the changes introduced in fc06fdeb76c89.  On
reflection, it doesn't make any sense to support what is actually
a Unix *report* mode in an API that does not report filenames.

File::Copy just needs to supply names to the underlying copy
functions that they can operate on.  How those names are presented
is of no concern here as we don't present them to the caller.
