Fix GSS per-message token edge cases

Change g_verify_token_header() not to modify *in when the ASN.1 length
does not match the expected value.  This edge case could result in
accepting an invalid ASN.1 wrapper when processing an RFC 1964 MIC or
wrap token.

Change decrypt_v3() to return GSS_S_BAD_SIG instead of GSS_S_FAILURE
when decryption fails, for specificity and consistency with previous
versions.
