P3K_FILES_TO_IGNORE has paths using slashes.

pylint 0.26.0 doesn't have the code. I confirmed "pip install pylint==0.26.0" passed.

Pylint 2.6.0 is Python >=3.5.*
Pylint 1.9.5 is Python >=2.7, !=3.0.*, !=3.1.*, !=3.2.*, !=3.3.*, <3.7

There is an open bug https://bugs.webkit.org/show_bug.cgi?id=204133
