Liblzma

- Added package dependency: liblzma* for .deb and .rpm. 
- There can be multiple libraries for different architectures on Debian Multiarch environment (e.g. /lib/i386-linux-gnu/liblzma.so.5 and /lib/x86_64-linux-gnu/liblzma.so.5), so I added code to select right one in linux/lightzone script.
- Added alternative package dependency: openjdk-7-jre for debian wheezy i386. (Note: reported by Jedd in 2013/6/15.)
