genelf: Use HAVE_LIBCRYPTO_SUPPORT, not the never defined HAVE_LIBCRYPTO

When genelf was introduced it tested for HAVE_LIBCRYPTO not
HAVE_LIBCRYPTO_SUPPORT, which is the define the feature test for openssl
defines, fix it.

This also adds disables the deprecation warning, someone has to fix this
to build with openssl 3.0 before the warning becomes a hard error.
