param-validation: make symbols hidden

This convenience library is linked statically with the various plugins
that use it.  The symbols are currently not marked as hidden, which
causes the plugins that use it (e.g. babeltrace-plugin-ctf.so) to expose
them publically.  Sad.

Mark the symbols as hidden to avoid that.
