    Use conditional to work around gtk+-3.0.vapi breakage
    
    Commit 53007652ce1ed3cf350ec042b310606e0115377a breaks the build with
    versions of Vala older than 0.35.6. It's more convenient for people
    building Tracker if we use a #if block instead to allow building with
    older stable versions Vala.
