openssl: use ASN1_ENUMERATED_to_BN() if needed

Browse Source 
* ext/openssl/ossl_asn1.c (asn1integer_to_num): Use
  ASN1_ENUMERATED_to_BN() to convert an ASN1_ENUMERATED to a BN.
  Starting from OpenSSL 1.1.0, ASN1_INTEGER_to_BN() rejects
  non-ASN1_INTEGER objects. The format of INTEGER and ENUMERATED are
  almost identical so they behaved in the same way in OpenSSL <= 1.0.2.
  [ruby-core:75225] [Feature #12324]

* test/openssl/test_asn1.rb (test_decode_enumerated): Test that it
  works.
