Upgrade to Mongo 3.6

Update the Meteor Tool to use Mongo 3.6.2 for 64-bit OS'
and Mongo 3.2.18 for 32-bit OS'. A few important mentions:

- As of Mongo 3.6, all Mongo binary downloads include
  SSL - there is no longer a non-SSL based download bundle
  (so it's a bit bigger, but that shouldn't be an issue).
- Using the `--nojournal` option with WiredTiger based
  replica sets is no longer supported (see
  https://jira.mongodb.org/browse/SERVER-30760). The
  `--nojournal` flag was added in
  bcfe072
  to help reduce the amount of disk space used by Mongo,
  but since this option is no longer supported, we'll
  have to live with the extra disk space usage.
