The subprocess.check_output() raises TypeError when given the `check` keyword-argument:

Python 3.8.2 (v3.8.2:7b3ab5921f, Feb 24 2020, 17:52:18)

>>> import subprocess
>>> subprocess.check_output(['ls'], check=False)
Traceback (most recent call last):

TypeError: run() got multiple values for keyword argument 'check'

It should just use True as the default when it's not specified in kwargs.
