busybox: enable dropping of duplicates in syslog, off by default

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.
