[OE-core] [RFC PATCH 3/5] busybox: enable log level configuration in syslog-startup.conf and script

[Joshua Lock]

It's possible to configure busybox syslog to only log messages above a
certain level, expose this functionality through the syslog-startup.conf
and syslog init script.

Valid values are 1-8 inclusive.
