[OE-core] [PATCH] 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 in the recipe that created
by devtool while leaving an option for users to enable them manually
if needed. Since devtool already has this options, we need to ensure
that recipetool is able to handle the options passed from devtool.
