Andrea Bolognani c587c73549 wireshark: Inject $(prefix) at the right time
Adding $(prefix) in Makefile.am, as we were doing, means that
it would be prepended even when using --with-ws-plugindir,
which is something we don't want to happen.

Instead, we add it beforehand but take care that it doesn't
get expanded until make is called.
