Yueh-Hsuan Chiang a8b8295d18 Fixed a compile warning in options_test.cc under clang 
Summary:
Fixed the following compile warning in options_test.cc under clang
util/options_test.cc:94:12: error: 'Skip' overrides a member function but is not marked 'override' [-Werror,-Winconsistent-missing-override]
    Status Skip(uint64_t n) {
           ^
./include/rocksdb/env.h:368:18: note: overridden virtual function is here
  virtual Status Skip(uint64_t n) = 0;
                 ^
