Tox/Zuul: Fix import-error pylint messages

The stx-utilities-tox-pylint zuul job is failing due to not
being able to import certain modules which are only available
during runtime.

To fix this, adjusted .pylintrc to ignore import errors for
these specific runtime modules.

In addition, renamed the pylint config file from "pylint.rc"
to the standard ".pylintrc"

Test Plan:
pass - Zuul test passing

Partial-Bug: 2110076
