DRILL-4050: Add zip archives to the list of artifacts in verify_release.sh

This enhanced version of the script allows integrated download and verification of a Drill release. It can be used to verify both the main release artifacts and maven repository artifacts.

For example, to verify the 1.6 rc0 release artifacts, I ran

./verify_release.sh https://repository.apache.org/content/repositories/orgapachedrill-1030/ /tmp/drill-1.6/maven/

./verify_release.sh http://home.apache.org/~parthc/drill/releases/1.6.0/rc0/ /tmp/drill-1.6/main/

If I had pre-downloaded the files in the respective folders, I'd run

./verify_release.sh /tmp/drill-1.6/maven/

./verify_release.sh /tmp/drill-1.6/main/

Finally, run with `-nv` option to reduce the verbosity of the output.

Closes #249.
