python3-pylint: omit failing pickle test

There is one test in the pylint suite involving pickling non-pickleable
plugins that fails on target (but not host). Disable this test for
ptest runs.

+Subject: [PATCH] pylint: remove plugin pickle test
+
+Upstream-Status: Inappropriate (oe-specific)
+
+Upstream uses an assertion in the removed test to state that the test
+needs changing if the plugin loading succeeds. The same failure wasn't
+seen when running the tests on the host with pytest, so disable it by
+removing the test from the suite.
