fb_spamassassin: Fix timer jobs (facebook#306)

Summary:
Somehow I had gotten it in my head when I wrote a bunch of these
cookbooks that timer jobs needed to `:enable`'d but `:start` would
run the actual job. That is, of course, not true, the underlying
_service_ can be started to do an immediate run.

As a result the update jobs never ran, when expected. This fixes that.
