Dereference potential linked launch.sh file

It can be useful to have launch.sh linked somewhere outside the
repository clone. For instance to expose launch.sh in the $PATH.

Exposing launch.sh with a symbolic link outside the git repository
breaks poezio execution through launch.sh. “ cd dirname "$0" ” will get
to the directory holding the link and not within the git repository.
