Fix for issues reported in the mailing list

I've fixed some of the issues reported in lightzone-dev mailing list:

  - To fix the 'ant clean' issue, some of the files removed. Autoconf, automake and libtool are now required to create Makefile for libjpeg-turbo.
  - Setup 64bit version of libmlib_jai.so when the build is on amd64 machines.
  - Debug option in packages for OpenSUSE and Ubuntu prevents from installation of Templates (*.lzt), so I removed that.
