From: Max Reitz <mreitz@redhat.com>

Both of the defaults we currently have in the curl driver are named
based on a slightly different schema, let's unify that and call both
CURL_BLOCK_OPT_${NAME}_DEFAULT.

While at it, we can add a macro for the third option for which a default
exists, namely "sslverify".
