sshd_log: allow both types GAUGE and DERIVE, default to GAUGE

Browse source 
In fact for journald mode internally it really is type ABSOLUTE, because
we use journald cursor to get only new logs on each collect. It results
in the same value as with a plain log file and type DERIVE: it's the
rate of events.

type=DERIVE is best for servers with lots of ssh traffic.
