On openSUSE Leap 15 (OpenSSL 3) the build fails compiling
src/plugins/lan/auth.c with "unknown type name MD2_CTX". OpenSSL 3
removed MD2 from the default provider but still installs a stub
openssl/md2.h, so configure's AC_CHECK_HEADER probe succeeds and defines
HAVE_CRYPTO_MD2 -- yet MD2_CTX and the MD2_* functions no longer exist,
so auth.c's MD2 code path will not compile. Export
ac_cv_header_openssl_md2_h=no in %build to force the probe negative,
selecting the existing no-MD2 branch (which just warns that MD2 IPMI
authcodes are unsupported -- an obsolete, insecure scheme). Systems with
a real md2.h are unaffected.
