Peter Schiffer 444be2c060 Log to file only if the file exists
If LOG_FILE config option contained invalid file, pdns admin wouldn't start.
Also, it wasn't possible to log only to stdout/stderr correctly, because
setting the log file to /dev/stdout would double the logs messages as the pdns
admin is already logging to the stderr.
