With commit 385200443554 ("babeld: add add_interface function") babeld
has a new ubus function allowing to dynamically add an interface.
Before the add_interface function, we were required to reload babeld.
The reload influenced the babeld routing. However, the remove part is
still missing and will be added at a later stage.

Use shellcheck to rework the code. Use "export" to return variables from
a function call. Further, fix typos.

Add a hotplug.d-extension that automatically configures babeld for
meshing via wireguard interfaces.
It checks for "add" and "remove" of a wireguard interface with name
"wg_*". Depending on the action, it removes it from the babeld config
or adds the interface and reloads babeld.
