syslog-ng [FIX]: make recent syslog-ng happy

A recent syslog-ng (OpenSuSE Tumpleweed, syslog-ng 3.7.1) complained because
of the strange and conflicting source definitions used here. In my opinion all
messages are simply passed internally. No need to tcp or /dev/log. Anyway, the
quickfix here makes things go well.
