More tidies to objcopy archive handling

This makes sure copy_archive exits with ibfd and obfd closed.  Error
paths didn't do that, leading to memory leaks.  None of this matters
very much.

	* objcopy.c (copy_archive): bfd_close ibfd and obfd on error
	return paths.  Remove braces around "list" free.
	(copy_file): Don't close invalid file descriptor.
