[Pkg-emacsen-addons] Bug#886024: a scenario with site file breaking installation of elpa packages

[H.-Dirk Schmitt]

Just another motivation to skip the site file on emacs addon package
installations

1. A software/configuration roll out has been issued.
2. Per site file „Company Mode“ has been enabled per default in our
organisational site file.
3. „apt-get“ step  is running and find the missing dependency for elpa-
company

Same Error as above – and also for all further emacs related addons.
