Added black magic to fix the phar rewrite issue

Black magic is described here:
https://mailman.archlinux.org/pipermail/aur-general/2014-March/027444.html

Also:

Now that you mentioned diffing, I realized that I forgot to write that I tried
it and diff said binary files /path1/gush.phar and /path/gush.phar differ. As
I wanted to include this in my reply, I double checked it and to my surprise
now it indicated they don't!

So I started to investigate... Tried running both. The installed version
didn't run, the non-installed one did. Tried diffing again, they differed. I
figured the first run must alter it some way - no idea why - so I run chmod
777 on it - and it worked!

Well, as I couldn't just leave it that way, I decided to try something else
and run ./gush.phar --version at the end of build(). It worked, so now it's
finally fixed. That shouldn't be too annoying, fixes the issue and is only a
minor black magic. I think I'll blog about this weird issue and fix...
