Hadoop 3 profile for hbase-shaded-mapreduce should like mapreduce as a provided dependency

the hadoop 3 profile currently misses declaring a provided dependency on the core mapreduce client module. that means we pick it up as a compile dependency from the hbase-mapreduce module, which means we include things in the shaded jar that we don't need to. (and expressly aren't supposed to include because they're supposed to come from Hadoop at runtime).
