    Append a default system-wide location to vmod_path
    By default: /usr/share/vcl
    This directory becomes a drop-in, and standard location for library-like
    VCL files. It streamlines third-party VCL packaging, offering a blessed
    for installation, leaving the canonical /etc/varnish directory entirely
    to the end-user.
    While it is common to see VMOD packages in the wild, there are some VCL
    libraries (sometimes backed by VMODs) that would benefit some form of
    standardization. It then becomes possible to install packages, and use
    relative includes that JustWork(tm). This is especially true for VCL
    libraries that are split into several files, they can put themselves in
    a subdirectory in /usr/share/vcl and use it as a namespace for includes
    between files of the library:
        # somewhere in my awesome "foo" library
        include "foo/some_feature.vcl"
    Choosing a default path of `/etc/varnish:/usr/share/vcl` prevents VCLs
    dropped in the system from shadowing end-users VCLs but at the same
    empowers said users to override a "standard" VCL in their `/etc` tree,
    with no additional parameters fiddling.
