[Buildroot] [PATCH v3 7/7] package/gupnp-dlna: add optional dependency for gobject-introspection

[aduskett at gmail.com <aduskett@gmail.com>]

From: Adam Duskett <Aduskett@gmail.com>

If gobject-introspection is selected, explicitly set --enable-introspection in
the configure options and add a dependency for both gobject-introspection and
host-vala.

Host-vala is necessary because the introspection includes vala bindings files
with no way to explicitly disable them.
