disable fields not available in varnish 2.0.x

Several fields were added in commit 8775392. 3 of them make the build
fail when varnish 2.0.x is used. This patch makes them available only
when using varnish 3.x.

The commit message of 8775392 gives more detail on the rationale behind
this way of doing.
