[PATCH] Fix File::Copy test failure on Windows

The attached patch fixes a failure in the new File::Copy tests added
by 43ddfa5614 (the ok(!copy...) test passes, but the
like($warn_message...) test fails because the code which sets the
expected warning isn't run on Windows).

However, I haven't applied it because it doesn't seem correct to me:
wouldn't it be more appropriate in this case for the copy to
"succeed", like the _eq($from, $to) case a few lines earlier in
Copy.pm does?

That can be achieved by changing the new return 0 which this patch
adds to return 1 and adjusting the test script accordingly, although
that would involve the test script replicating the same d_symlink /
d_readlink / d_link logic as Copy.pm has, which doesn't seem ideal
(unless *that* case is also changed to return 1...).
