GH-40863: [C++] Fix TSAN link error for module library (#40864)

### Rationale for this change Module library `arrow_filesystem_example` is introduced in #39067 for filesystem testing: https://github.com/apache/arrow/blob/6cecbab5172b2b339277dde741bfff455646eb32/cpp/src/arrow/testing/CMakeLists.txt#L25 However when built with TSAN, linker flags such as `-fsanitize=thread` is not set, causing the link error in #40863. ### What changes are included in this PR? Add necessary linker flags for module library. ### Are these changes tested? Manually tested. ### Are there any user-facing changes? None. * GitHub Issue: #40863 Authored-by: Ruoxi Sun <[email protected]> Signed-off-by: Antoine Pitrou <[email protected]>
