CryptoPkg/BaseCryptLib: Use accessor functions for X509_ATTRIBUTE
In OpenSSL 1.1, the X509_ATTRIBUTE becomes an opaque structure and we will
no longer get away with accessing its members directly. Use the accessor
functions X509_ATTRIBUTE_get0_object0() and X509_ATTRIBUTE_get0_type()
instead.
Also be slightly more defensive about unlikely failure modes.
