Switch from flags to an 'additional repository' menu (#977)

* Add multilib flag to enable this repository and enable multi-lib testing if testing flag is also passed

* Fix comments

* Attempt to force pacman to use the config file from the host

* Make sure the pacman configuration is copied to target

* flake8

* Call enable on additional-repositories

* Add method to select additional repositories

* Add menu option for additional repos

* This is a bit cleaner than having it all on one line

* Add import

* Use [] as default instead of None

* Use empty array for default option here

* Try this to ensure a valid array is returned on skipping

* Add additional-repositories to schema

* Missed changing this comment earlier
