(read|append)_config_file: log open errors as LOG_DEBUG

In a "decentrally managed vpn" it is very likely that host config
files for some reachable nodes do not exist. Currently, tinc
fills the logs with "Cannot open config file" messages.

This commit changes the log level to LOG_DEBUG so
syslog doesn't get filled by default.
