refactor(nodetool): only add libs when necessary

[zmstone]

Fixes EMQX-11191

Summary

The nodetool command is started in a temp remsh node which mostly issues RPC to the running EMQX node.
For example, ctl, ping and status
However, hocon and check_license_key commands are executed locally (meaning there is no need for a running EMQX node in order to execute the command), so it needs to load all the apps before executing the command.

Prior to this fix, the loading of the emqx apps is unconditional, the apps are loaded even if it's just a plain RPC call.
The fix is to only load apps for hocon and check_license_key.
