    meson: Fix GIR generation
    
    The generated GIR information does not include proper header
    location, which makes packages depending on libgit2 GIR
    information not to build properly.
    
    It is also missing the package name and also enums types
    information due to not including generated enums files.
    
    This patch fixes these issues.
