test: Add test for fpsensor trivial key failure
Add a test for derive_positive_match_secret when compute_hmac_sha256 returns a trivial key (either 0x00 or 0xFF). This required mocking compute_hmac_sha256 to get the proper test behavior. Since other tests depend upon a proper SHA256 hash to be generated, either all key/message combinations would need to be mocked or some calls to compute_hmac_sha256 need to be passed through to hmac_SHA256. The latter option was chosen for the best flexibility moving forward.
