Review comment:
Originally `FlinkDistributionOverlay` uses the `TARGET_ROOT` to set the
`ENV_FLINK_HOME_DIR`. But if the `Path TARGET_ROOT = new Path(Path.CUR_DIR)`
the `TARGET_ROOT.toString()` is empty.
This will lead `MESOS_TM_CMD`[1] to `/bin/mesos-taskmanager.sh` which can
not launched the TM.

key("mesos.resourcemanager.tasks.taskmanager-cmd")
.defaultValue("$FLINK_HOME/bin/mesos-taskmanager.sh"); //
internal`
