Subject: Verify dependencies for build_nexus_blob.sh are installed

Script now checks if utilized tools are installed on the
system. Without that it would fail in the middle of the flow.
Now it will fail fast at the beginning if a particular dependency
is missing. It will also list those missing dependencies.
