[RFC][icedtea-web]: PR1049 fix - extension jnlp with empty jars

[Saad Mohammad]

Hi Adam,

Sorry for multiple emails but it seems like the patch command does not like
empty files too much :(. The previous patch was not creating the new empty file
because it had no content
(tests/reproducers/signed/EmptySignedJar/srcs/META-INF/emptyFile).

I have fixed this problem in the updated reproducer patch attached. This patch
contains two filename changes and an added test.

I have attached the PRO1049 fix in my previous email with some comments. Please
let me know if you run into any problems. Sorry again for all the trouble.

Thanks.
