Andrew Ayer 958e7a9efb Avoid relying on STH timestamp during monitoring
Instead use the time at which the STH was observed (which for
FilesystemState is assumed to be the mtime of the STH file).  This is
easier to reason about: we don't have to worry about logs lying about
the time; we don't have to take into account the delay between STH fetch
and healthcheck; we won't raise spurious health checks about logs with
MMDs longer than the healthcheck interval.
