[OE-core] [PATCH 5/5] busybox: enable dropping of duplicates in syslog, off by default

[Joshua Lock]

Busybox syslog includes functionality to drop duplicated syslog entries,
enable this feature in the defconfig yet disable it by default.

Expose configuration of the feature through the syslog-startup.conf file
and the syslog init script.
