    Install cache/cache_varnishd.h as part of $ABI strict
    
    This removes the need for non-VRT VMODs to require a Varnish source tree
    to build, especially since varnish.m4 only supports Varnish installations
    today and would leave VMOD authors on their own in order to build from
    a source tree. Since $ABI defaults to strict, any VMOD author actively
    choosing vrt compliance is responsible for ensuring it only uses blessed
    symbols.
    
    In our official packages, they land in the varnish-dev deb and the
    varnish-devel RPM:
    
        $ rpm --query --package --list varnish-trunk-1.el7.x86_64.rpm |
        > grep cache_varnishd.h
    
        $ rpm --query --package --list varnish-devel-trunk-1.el7.x86_64.rpm |
        > grep cache_varnishd.h
        /usr/include/varnish/cache/cache_varnishd.h
    
    You will have to trust me for the Debs as it's a bit cumbersome for me to
    build them locally.
