Only allocate the space we need before calling kern_getgroups instead
of allocating what ever the user asks for up to "ngroups_max + 1".  On
systems with large values of kern.ngroups this will be more efficient.

The now redundant check that the array is large enough in
kern_getgroups() is deliberate to allow this change to be merged to
stable/8 without breaking potential third party consumers of the API.
