fix(machine_boot): inject connector/bridge apps as dependencies to emqx_connector app

[thalesmg]

For the same reasons as we inject emqx_bridge_* applications as dependencies to emqx_bridge when starting the node. Already configured connectors are started when emqx_connector application starts, and may lead to crashes and noise in the logs. One example is to configure a mongodb bridge and restart the node.

Thanks to @SergeTupchiy for noticing this. 🍻

Release version: v/e5.5

Now only these apps depend on emqx_connector (which starts before emqx_auth according to reboot_lists.eterm):
