lib/oe/recipeutils: fix line splitting in patch_recipe_*
If a value was split over multiple lines (e.g. as SRC_URI usually is)
then we were inserting the value as one item in the lines list with
newlines between each line. There's nothing wrong with this if you're
writing the list out to a file, but if you want to generate a patch (as
patch_recipe_file() will do if the patch parameter is set to True) then
the diff output looks a bit odd. Split the value before adding it to the
lines list to resolve this.
