End commandline with a newline

Due to a [recent change](https://github.com/Icinga/icinga2/commit/0a6505ce2d778d46863345ad7b457cbe911a3176#diff-41f5f9b62fd89e63b82e66bbe76c0e73R121) in Icinga, commands passed through the external command listener are read by _readline_ so that's mean they have to be ended by a newline.
