[Kaffe] patch for problems with zip extraction

[Moses DeJong]

Hello.

Here is a patch for SwitchInflater.java that fixes zip extraction
for uncompressed files. I can provide code that proves that this
fixes the problem but this is really a "no duh" fix so I am not
going to send source code in this email.

	* libraries/javalib/kaffe/util/zip/SwitchInflater.java
	Fixed problem that caused uncompressed zip streams to be
	read past the zip entry size.
