certtool --p12-info will print invalid information on unsupported PBES2 schemas
When decoding an unsupported schema from PKCS#12, certtool will print:
Schema: unsupported (1.2.840.113549.1.5.13)
However that OID is the PBES2 OID which is certainly supported. We should print instead the internal encryption OID that was not supported.
