Script ./install.sh does not work if adding mqtt as parameter

[andreasg86]

On the wiki on page:
https://wiki.volkszaehler.org/software/controller/vzlogger/installation_cpp-version#systemd_startscript
there is recommended to use to following instruction
./install.sh mqtt

But the script does not install vzlogger and the other stuff.

The problem is, that if no argument (-z) will be given to the install.sh script every component will be installed, except "mqtt". That's ok.
But if you add any component to the shell script, for example "./install sh mqtt" then "-z" is not fulfilled and the other components of vzlogger (except mqtt) won't be installed.

[J-A-U]

I changed the Wiki for workaround. Use ./install.sh vzlogger libjson libsml mqtt for a complete installation.

For the team: Maybe we don't want to exclude mqtt anymore?
