HBASE-23793 Increase maven heap allocation to 4G in Yetus personality…

[ndimiduk]

… (#1122)

I saw this over on
https://builds.apache.org/view/H-L/view/HBase/job/HBase%20Nightly/job/branch-2/2447/console. Looks
like we need to bump the memory allocation for maven. I wonder if this
is the underlying cause of HBASE-22470.
