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.
