pkg/list: adding flattenN function as a builtin

this commit adds a new builtin to the list package for generating a
flat list from a nested list by expanding nested lists in place. only
nested lists n levels deep into the structure are expanded.

for instance

    list.FlattenN([1, [[2, 3], []], [4]], 1)

results in

    [1, [2, 3], [], 4]
