To keep compatibility with any existing object authValues with trailing 0's, change tpm2_get_pin_auth() to trim trailing 0's, which is what the TPM implementation will do. This should retain compatibility with any existing authValues that contain trailing 0's. Note that any existing authValues with trailing 0's are unlikely to have worked in the way that systemd uses them in object sealing, which is as a bind key for the encryption (and policy) session. However, it is better to be compatible with the TPM spec (and implementations) even if previously created objects that are affected may not have worked. Fixes: #28414
