[SPARK-3710] Fix Yarn integration tests on Hadoop 2.2.

It seems some dependencies are not declared when pulling the 2.2
test dependencies, so we need to add them manually for the Yarn
cluster to come up.

These don't seem to be necessary for 2.3 and beyond, so restrict
them to the hadoop-2.2 profile.

Closes #2682 from vanzin/SPARK-3710 and squashes the following commits:
