Test an approximation of an OPAM install / uninstall of a plugin package
This takes the sites-plugin.t blackbox test extracted from the manual and
changes its end to cover:
- dune install of both the application and its plugin,
- dune uninstall of the plugin, leaving an empty directory as OPAM would.

$ dune build @install
$ dune install --prefix _install

Registration of Plugin1
Main app starts...
Plugin1 is doing something...
$ dune uninstall --prefix _install plugin1
Unfortunately, the fact that the `lib/app/plugins/plugin1` directory should be
removed along with plugin1 is lost in the OPAM metadata, so we simulate this
issue by recreating this empty directory.
$ mkdir -p _install/lib/app/plugins/plugin1
$ OCAMLPATH=_install/lib:$OCAMLPATH _install/bin/app
Main app starts...
