Check whether any mmapv1 options are supplied to other storage engines

Follow-on from SERVER-25008:

A more complete solution might be:

1. move repairpath into MMAPV1Options struct, so that it lives with all the
   mmapv1-specific options, and
2. enforce all the mmapv1-specific options the same way, not just repairpath.
   E.g., the server should also fail to start up if you use "quotafiles" or
   "nopreallocj" without mmapv1.
