Validate logger priority and tag with logger -f /dev/null
Validate logger priority and tag with logger -f /dev/null

Previously, daemon validated logger priority and tag strings by calling
logger -p PRIORITY -t TAG with stdin closed. However, the logger
included in newer versions of GNU Coreutils hangs when run this way.
Invoking logger with -f /dev/null achieves the intended effect and works
on all versions of logger.
