osdmon: set the maps-to-keep floor to be at least epoch 0

Looks like this conditional was just set backwards by mistake. There
have been a number of issues with OSDMap versions that are probably
related to this...
(Thanks to some smarts in trim_to, we at least did not trim ALL of
our maps. But on every tick prior to epoch 500 [that's the default]
the leader was trimming all old maps off the system.)
