selftests: bpf: Reset global state between reuseport test runs

Browse source

[ Upstream commit 51bad0f056 ]

Currently, there is a lot of false positives if a single reuseport test
fails. This is because expected_results and the result map are not cleared.

Zero both after individual test runs, which fixes the mentioned false
positives.
