The script used the logger utility unconditionally but it may not exist
(e.g. busybox-minimal.config is used and BR2_PACKAGE_UTIL_LINUX_LOGGER
is not selected).
Declare two functions to perform the operation, run_logger and run_std,
and use the appropriate one, depending on the existence of logger.
