all: add default log file if none are defined

Added a default log file named /var/log/quagga/Quagga.log to every daemon
to capture log entries if no log file is defined.  This also allows the
capture of logged information prior to reading each daemon's config file.
If a log file is defined manually, it will override this default file name.
