scripts/aglsetup: remove duplicate features before generating config

With features dependencies, it may happen that the final list of features
to handle contains duplicates. With recent changes on configuration fragments, this
produces some WARNINGS due to multiple inclusions of the same file in the
generated local.conf
.
This commit cleans up the features list resolved internally by removing duplicates
before generating local.conf
