as_string gives wrong result for keyword-only arguments

Given the following code, calling as_string on the resulting module leads to a surprising output:

#!python

from astroid import parse
m = parse('''
def test(a, b, c=42, *, x=42, **kwargs):
    print(a, b, c, args)
''')
print(m.as_string())

It seems that keyword only arguments are somehow treated as annotations.

#!python

def test(a, b, c=42, **kwargs, *, x:42):
    print(a, b, c, args)

It's partially fixed. The resulting output it's still not valid syntax.
