Fix failing "android-safetynet attestation" test

[grzuy]

Started failing because of the certificate used in the test expired in December, causing validation to fail.

Timecop doesn't work as the check happens inside OpenSSL/C. I've tried to get around that by using libfaketime, but I'm getting delayed results when dynamically changing the faked time via the environment variable 🤔

Thank your for looking into this!

Bummer. Getting timecop working for this would have been ideal.

Workaround could be having a new attestation in the test seeds.rb with a certificate expiring very very far in the future, right?
