Unable to create cache directory

[GergelyKalmar]

Bug description

I have a test that runs a pytest session using Pytester and executes pylint through the pytest-pylint plugin. Under these circumstances I'm getting the following error:

tests/pytest_project/test_core.py::test_run_errors Unable to create directory /tmp/pytest-of-user/pytest-1/test_run_errors0/.cache/pylint
Unable to create file /tmp/pytest-of-user/pytest-1/test_run_errors0/.cache/pylint/test_run_errors1.stats: [Errno 2] No such file or directory: '/tmp/pytest-of-user/pytest-1/test_run_errors0/.cache/pylint/test_run_errors1.stats'

If I create the .cache folder manually it succeeds. However, it would be great if pylint could create the necessary parent folders are well when trying to create the pylint folder inside XDG_CACHE_HOME.

Command used

Pylint is invoked indirectly through pytest-pylint.

Pylint output

See error above.

Expected behavior

I would expect that the Pylint cache folder creation succeeds even if XDG_CACHE_HOME does not exist.

Pylint version

pylint 2.10.2
