Fixed missing libudev.so.0 after downloading packages for Linux x86

I have made a fix for error occuring on most of linux-x86 distributions:
```
error while loading shared libraries: libudev.so.0: cannot open shared object file: No such file or directory
```
The fix is based on **Troubleshooting** chapter from official `node-webkit` repository:
https://github.com/rogerwang/node-webkit/wiki/The-solution-of-lacking-libudev.so.0
I have tried every solutions, but for packaged applications, the best (and working) solution is `sed`-ding an `nw` executable. 
I have no option to test if `nw` works in x64 OSes without that fix, so I've made restriction for x86 only. Moreover it is temporary solution, we need to wait for `node-webkit` developers to fix that bug in their lib.
