main: use syslog & printf directly for early log messages

libqb seems funny about logging things before its fully configured.
This corosync commit didn't help either:
8b6bd86a55b8bda9f3a8ff67bdff908263976fa3

So to make sure that messages about the config file not being opened
get delivered to the user/syslog we send them directly.
