Subject: fix(dracut-logger.sh): this fixes the dlog_init check for /dev/log

fix(dracut-logger.sh): this fixes the dlog_init check for /dev/log

The /dev/log check was not correct, it would continue working if
/dev/log was a broken symlink. This changes the logic to be more clear
-- /dev/log needs to be a socket, and writable, and logger needs to be
available. If any of those conditions fail, turn off syslog and only use
console logging.
