Add ws-clean permission for non-CM nodes

Previously changed jenkins-sudo-inst.sudo file. Forgot that only
applies to nodes using trafodion installer. Need to add same
permission to the jenkins-sudo-hbase.sudo file to apply to other
nodes.

Since jenkins environment variables do not pass thru sudo command,
WORKSPACE must be passed on command line.

Also remove the echo from ws-clean to actually execute the rm
commands.
