Backport upstream commit 5e698b407dcac2bc45cf03484bac4398109d25c3 to fix
missing intermediate certificate validation in Freeradius2.


The FreeRADIUS server relies on OpenSSL to perform certificate
validation, including Certificate Revocation List (CRL) checks. The
FreeRADIUS usage of OpenSSL, in CRL application, limits the checks to
leaf certificates, therefore not detecting revocation of intermediate CA

An unexpired client certificate, issued by an intermediate CA with a
revoked certificate, is therefore accepted by FreeRADIUS.

Specifically sets the X509_V_FLAG_CRL_CHECK flag for leaf certificate
CRL checks, but does not use X509_V_FLAG_CRL_CHECK_ALL for CRL checks on
the complete trust chain.

The FreeRADIUS project advises that the recommended configuration is to
use self-signed CAs for all EAP-TLS methods.
