[SPARK-18750][YARN] Avoid using "mapValues" when allocating containers. 

That method is prone to stack overflows when the input map is really
large; instead, use plain "map". Also includes a unit test that was
tested and caused stack overflows without the fix.

Closes #16667 from vanzin/SPARK-18750.
