'service quagga reload' should not dump so much output to the log file.

It should also check that quagga is running before attempting to do
any work.

Testing Done:

Verified that 'service quagga reload' exits cleanly if quagga is not
running.  Also verified that it produces a minimal amount of log output
by default.  The user can enable --debug in /etc/init.d/quagga if they
would like to enable debug output.
