Draft: Invert mirror selection's protocol handling to prefer https if present for domain in list

copy paste from #2062 (closed)

Hello,

first of all thank you for your awesome work! I am newbie to whole pine64-postmarket-oss contribution workflow anyway I would like to submit my local changes in case anyone faces same issue.

I was surprised http is prefered protocol accepted in !2035 (merged) I would like to invert this behaviour and prefer https protocol if available for domain.

In case it's intentional I was not aware of it.And would gladly appreciate any input.
