gh-120526: Correct signature of map builtin

map requires at least one iterable arg. If you just do `map(map)` you get an error "map() must have at least two arguments." This corrects the signature to reflect this, in line with how it's shown in https://docs.python.org/3/library/functions.html#map . Signed-off-by: Adam Williamson <awilliam@redhat.com>
