[OE-core] [PATCHv2 1/4] recipetool: create: disable PREMIRRORS and MIRRORS by default

[Chang Rebecca Swee Fun]

When creating new recipes, we are almost certainly fetching a new
source rather that something that has already been fetched. I have
disable PREMIRRORS and MIRRORS settings from datastore while leaving
an option for users to enable them manually if needed.
