Porting Lutris over

[Marlin]

I have started porting Lutris, i'm getting errors about GObject bindings
and the lack of typelib (which is weird, because i did port typelib too)
I'd appreciate some help with this, as i'll be travelling and won't be
able to spend much time on it.
The packages are lutris.scm and typelib.scm, located on my personal
channel https://framagit.org/marlin1113/marlin-guix-packages
