bin2res should open binary files in binary mode

[Pavel Roskin <proski@gnu.org>]

Hello!

When winefile is compiled on Windows, the folder icons are corrupted.
This happens because bin2res opens the binary resource files in the text
mode and adds "\r" before some occurrences of "\n".

This patch makes bin2res open binary files (icons and bitmaps) in the
binary mode, both for reading and writing.  POSIX systems are not
affected.

wrc already uses "rb" and "wb" when dealing with binary files.

ChangeLog:
	* tools/bin2res.c:
	Read and write binary files in binary mode on Windows.
