Add output truncation flag
This commit adds a "truncate" flag that can be added to a service description between the "tty" keyword and the path string. If the flag is set, the output file is truncated to 0 after opening. This probably requires some remodeling in the future as the tty keyword no longer deals with just tty devices. Signed-off-by: David Oberhollenzer <david.oberhollenzer@tele2.at>
