net/coova-chilli: fix -Werror=misleading-indendation

As it currently stands, the version of coova-chilli the packages feed
will not compile against 4fd87220567f1ae3ad209da1f602dc81c6b4d6b1

I've quasi-backported (could not find a single commit which fixes these
particular issues) https://github.com/coova/coova-chilli 's formatting
on the impacted sections, and it compiles.

Once a new version is added to the feed this patch can likely be
dropped.
