[Buildroot] [PATCH 6/8] sysklogd: add logging configuration file

[Carlos Santos <casantos@datacom.com.br>]

Provide a template to help users to customize syslogd and klogd without
editting the startup script. Also warn about options that must not be
used.

syslogd options worth to configure are mark interval (-m), remote log
support (-r) and domain list (-s).

Give example of how to configure klogd re-initialization signal.
