openssl: fix the Year 2038 problem

r55219 didn't fix the entire issue. It only fixed the issue on
environment with sizeof(time_t) == 8 && sizeof(long) == 4.

* ext/openssl/extconf.rb: Check existence of ASN1_TIME_adj(). The old
  ASN1_TIME_set() is not Year 2038 ready on sizeof(time_t) == 4
  environment. This function was added in OpenSSL 1.0.0.
  [ruby-core:45552] [Bug #6571]

* ext/openssl/ossl_asn1.c (ossl_time_split): Added. Split the argument
  (Time) into the number of days elapsed since the epoch and the
  remainder seconds to conform to ASN1_TIME_adj().
  (obj_to_asn1utime, obj_to_asn1gtime): Use ossl_time_split() and
  ASN1_*TIME_adj().

* ext/openssl/ossl_asn1.h: Add the function prototype for
  ossl_time_split().

* ext/openssl/ossl_x509.[ch]: Add ossl_x509_time_adjust(). Similarly to
  obj_to_asn1*time(), use X509_time_adj_ex() instead of X509_time_adj().

* ext/openssl/ossl_x509cert.c, ext/openssl/ossl_x509crl.c,
  ext/openssl/ossl_x509revoked.c: Use ossl_x509_time_adjust().
