summary:

gh-95349: Hide a Distutils Warning Filter for test_check_c_globals (GH-95837) (GH-95843)

Under certain build conditions, test_check_c_globals fails.  This fix takes the same approach as we took for gh-84236 (via gh-20095).  We'll be removing use of distutils in the c-analyzer at some point.  Until then we'll hide the warning filter.
(cherry picked from commit 3ff6d9affb351292ad8530802e7c06f651520706)
