[SPARK-3787][BUILD] Assembly jar name is wrong when we build with sbt omitting -Dhadoop.version

This PR is another solution for When we build with sbt with profile for hadoop and without property for hadoop version like:

    sbt/sbt -Phadoop-2.2 assembly

jar name is always used default version (1.0.4).

When we build with maven with same condition for sbt, default version for each profile is used.
For instance, if we  build like:

    mvn -Phadoop-2.2 package

jar name is used hadoop2.2.0 as a default version of hadoop-2.2.
