prunsrv: stdout/stderr redirection does not work if log directory didn't exist

If you enable stdout/stderr redirection (auto) and the log directory (given by LogPath) does not exist then Procrun will create the missing directory and will create the files commons-daemon-xxxx-xx-xx.log, ...-stdout-xxxx-xx-xx.log, and ...-stderr-xxxx-xx-xx.log, but the two latter files won't be populated (filesizes stay at 0).

Instead of fixing this issue in Procrun itself, imho, it might be sufficient to state this limitation in the documentation.
