[librsvg/alatiera/1-34-pin] rsvg_internal: Pin string_cache dep to 0.7.3

    rsvg_internal: Pin string_cache dep to 0.7.3
    
    The 0.7.4 release started using API which was introduced in rust
    1.36+ which bumped our minimum rust requirment from 1.34.
    
    Pinning the crate here gets cargo to prefere that version and not
    vendor the newer one, making it possible to build again with 1.34.
    
    Close #516
