Replaced distutils in test_image_access.py

[radarhere]

For #4796, similar to #4809

Replaces

from distutils import sysconfig

with

import sysconfig

and

sysconfig.get_python_inc()

with

sysconfig.get_config_var("INCLUDEPY")

Also removes a print statement.

However, this test is skipped on CIs, so this PR passing is not good evidence that my changes are correct. Instead, I created radarhere@73f8d40 to check that the values with and without distutils are the same - passing on AppVeyor and MSYS2 MINGW32.

In a move that's up for debate, I've added another commit, so that distutils is no longer explicitly imported - instead, I'm importing the distutils function from where it is imported in setuptools.

Thank you!
