llmnrd: set stdout to line buffering
The log output of llmnrd works well when operated from a terminal; but not when its stdout is piped to a log-file or -tool; due to buffering: By default, stdout is buffered (line buffered if connected to a terminal), and stderr is unbuffered. [1] Changing stdout to line buffering fixes this. [1] https://www.gnu.org/software/libc/manual/html_node/Buffering-Concepts.html
