Automatically set the absolute path of the program in the wrapper script

In order to keep the wrapper script open_wrapper.sh simple and solid,
the absolute path of conversations_http_downloader.py is used, however
the hardcoded example value can confuse some users, because the path is
not valid on their system.

So use a Makefile so replace the value automatically.
