Lookup gzdoom pk3 files in the installed directory in
addition to the path that is stored in ~/.config/gzdoom/.

configfile pointing to outdated guix builds, which could get
garbage collected and break the gzdoom installation.
This ensures that the files installed with the corresponding
build will be used.
