[gobject-introspection] Fix build reproducibility

    Fix build reproducibility
    
    ba744068 ("Make meson.override_find_program working on more complex use
    cases") made the build no longer reproducible by encoding a build system
    path into the output. This shouldn't be necessary anyway, since it
    should be possible to add new paths to search for gir files by setting
    the XDG_DATA_DIR environment variable.
    
    Closes #318
