Commit b982112a8d0b963cc7bfa23006934f43eb2eb6e8 revises this test to check that a valid suppression silences a report, instead of checking that an invalid suppression is rejected (this also removes the need for `UNSUPPORTED: ubsan-tysan`).

(Let me know if you'd still like a separate test to check that invalid suppressions are rejected.)
