Partly taken from my database, partly from @ryanmusante's.
Also update the sorting to match what modprobed-db outputs, so that it's
easier to check which modules are missing from the diet config.
* prepare: remove prompt for modprobed.db
it's an advanced feature, we don't want to prompt it
just like with TCP congestion algos
* add "_kernel_on_diet" customization option
A little less sugar intake is always welcome
this option hopefully helps with building kernels in github ci
* prepare: fix typo in var name $_where
the underscore was forgotten all this time...
* ci: enable _kernel_on_diet
* ci: move away from deprecated feature
the new approach is better actually too
