Using CMake's check_cxx_compiler_flag to check support for -Wthread-safety.
Previously used check_cxx_source_compiles to attempt a
build to determine support for clang thread safety checks.
This change is to support static analysis of the leveldb source by
lgtm.com (using Semmle). It failed to build with the following error:
```
[2019-07-04 22:29:58] [build] c++: error: unrecognized command line option ‘-Wthread-safety’; did you mean ‘-fthread-jumps’?
[2019-07-04 22:30:02] [build] make[2]: *** [CMakeFiles/leveldb.dir/build.make:66: CMakeFiles/leveldb.dir/db/builder.cc.o] Error 1
```
