    rocksdb: Fix build failure due to GCC9 deprecated-copy pessimizing-move
    
    GCC9 introduce more stricter checks deprecated-copy and pessimizing-move, while
    rocksdb uses -Werror and causes the following build error.
    
    db/version_edit.h:178:33: error: implicitly-declared 'constexpr rocksdb::FileDescriptor::FileDescriptor(const rocksdb::FileDescriptor&)' is deprecated [-Werror=deprecated-copy]
    
    utilities/persistent_cache/persistent_cache_util.h:51:23: error: moving a local object in a return statement prevents copy elision [-Werror=pessimizing-move]
