DRILL-7165: Redundant Checksum calculating for ASC files

[vdiravka]

• change 'checksum-maven-plugin' 'goal' - 'artifacts' -> 'files'
• specify 'includes' in 'fileSet' for 'checksum-maven-plugin'

@sohami Couold you please review?
Here is one not mandatory change: drill-root -> apache-drill project artifactId.
It is more convenient to use it as a parameter ${project.artifactId} or ${project.parent.artifactId} instead of hardcoding apache-drill everywhere.
The question is it safe to change Drill project artifactId? Looks like drill-root isn't used by external tools.
Not sure there are other risks to rename it. If they are, please let me know.

@vdiravka - I would recommend handling the rename change in separate PR rather than doing now if there is even slight risk of it breaking anything.

@sohami PR for project root POM ArtifactId rename is created: #1746
