Backport fix for API breakage of SSL_get_verify_result() introduced in
v5.1.1-stable. In v4.8.1-stable SSL_get_verify_result() used to return
X509_V_OK when used on LE powered sites or other sites utilizing
relaxed/alternative cert chain validation feature. After an update to
v5.1.1-stable that API calls started returning X509_V_ERR_INVALID_CA
error and thus rendered all such connection attempts imposible:
