Kefu Chai cc1d4e3d33 gcc-11 and cmake related cleanup (#9286)
Summary:
in hope to get rockdb compiled with GCC-11 without warning

* util/bloom_test: init a variable before using it
  to silence the GCC warning like
  ```
  util/bloom_test.cc:1253:31: error: ‘<anonymous>’ may be used uninitialized [-Werror=maybe-uninitialized]
   1253 |   Slice key_slice{key_bytes, 8};
        |                               ^
  ...
  include/rocksdb/slice.h:41:3: note: by argument 2 of type ‘const char*’ to ‘rocksdb::Slice::Slice(const char*, size_t)’ declared here
     41 |   Slice(const char* d, size_t n) : data_(d), size_(n) {}
        |   ^~~~~
  util/bloom_test.cc:1249:3: note: ‘<anonymous>’ declared here
   1249 |   };
        |   ^
  cc1plus: all warnings being treated as errors
  ```
* cmake: add find_package(uring ...)
  find liburing in a more consistent way. also it is the encouraged way for finding a library.
