Print out the error if testing for lgi failed.

This will be swallowed by Meson, so is not noisy, but will appear in the logs
for easier debugging.

Testing Done:
Compiled in mingw, which has some path issues with Lua, which can now be found in the error in the logs.

GPlugin is a GObject based library that implements a reusable plugin system.
It supports loading plugins in multiple other languages via loaders. It relies
heavily on [GObjectIntrospection](https://gi.readthedocs.io/) to expose its API
to the other languages.
It has a simple API which makes it very easy to use in your application.
For more information on using GPlugin in your application, please see the
[embedding](https://docs.pidgin.im/gplugin/latest/chapter-embedding.html) page.
