Relocate the `attestationChallenge` length validation from `generateSoftwareKeyPair` to `generateCertificateChain`.
The challenge is only utilized during the construction of the certificate chain (via `AttestationBuilder.buildKeyDescription`). Placing the check in the key pair generation stage caused the logic to miss the `attestKey` transaction hook in `KeystoreInterceptor`.
This fixes a bug introduced in ce740542f7 which missed the detection bypass for Android 10 and 11 devices.
