nix-doc: allow building without plugin

Browse source 
In certain situations, such as running development builds of Nix that
might break API, it can be undesirable to have a Nix dependency for
nix-doc, and there is still substantial useful functionality (ctags,
search) exposed in its binaries. Thus let's make it possible to turn off
the plugin build.
